Some Wikipedia articles include sound or video files, which can be played on almost all personal computers. However, your computer must have the right software. If your computer does not automatically play these files when you click on them, downloading and installing free software from the internet can enable it to do so.

Sound files on Wikipedia generally use the Vorbis audio format, and video files use the Theora format, both contained in an Ogg file. These are analogous to other formats used to play digital audio and video such as MP3 and MPEG. However, Microsoft Windows and Mac OS X do not support these formats by default, and require additional software to play them (see below).

Music files may occasionally use the MIDI format (.MID or .MIDI extension). MIDI is generally playable without additional software, as most computers have a MIDI-enabled player and sound card.

For help making and converting video and audio into the format usable on Wikipedia, see Wikipedia:Creation and usage of media files.

Jimmy Donal "Jimbo" Wales ( /ˈdoʊnəl ˈweɪlz/; born August 7, 1966) is an American Internet entrepreneur best known as a co-founder and promoter of the online non-profit encyclopedia Wikipedia and the Wikia company. Wales was born in Huntsville, Alabama, United States, where he attended Randolph School, a university-preparatory school, then earned bachelor’s and master’s degrees in finance. While in graduate school, he taught at two universities, but left before completing a PhD in order to take a job in finance and later worked as the research director of a Chicago futures and options firm. In 1996, he and two partners founded Bomis, a male-oriented web portal featuring entertainment and adult content. The company would provide the initial funding for the peer-reviewed free encyclopedia Nupedia (2000–2003) and its successor, Wikipedia.

On January 15, 2001, with Larry Sanger and others, Wales launched Wikipedia, a free, open content encyclopedia that enjoyed rapid growth and popularity, and as Wikipedia’s public profile grew, he became the project’s promoter and spokesman. He is historically cited as a co-founder of Wikipedia, though he has disputed the "co-" designation, declaring himself the sole founder. Wales serves on the Board of Trustees of the Wikimedia Foundation, the non-profit charitable organization he helped establish to operate Wikipedia, holding its board-appointed "community founder" seat. In 2004, he co-founded Wikia, a for-profit wiki-hosting service. His role in creating Wikipedia, which has become the world’s largest encyclopedia, prompted Time magazine to name him in its 2006 list of the world’s most influential people.

Randal Howard "Rand" Paul (born January 7, 1963) is the junior United States Senator for Kentucky. He is a member of the Republican Party. A member of the Tea Party movement, he describes himself as a "constitutional conservative" and a libertarian. He is the son of Republican Congressman and 2012 Republican presidential candidate Ron Paul of Texas and had never previously held political office. Paul first received national attention in 2008 when making political speeches on behalf of his father. Rand Paul is the first United States Senator in history to serve alongside a parent in the United States House of Representatives.

A graduate of the Duke University School of Medicine, Paul has been a practicing ophthalmologist in Bowling Green, Kentucky, since 1993, and established his own clinic in December 2007. In 1994, he founded Kentucky Taxpayers United, of which he is still the chairman.

In 2010, Paul ran as the Republican candidate for the United States Senate seat being vacated by retiring Senator Jim Bunning of Kentucky and defeated Kentucky Attorney General Jack Conway. As a supporter of the Tea Party movement, Paul has been vocal in advocating for term limits, a balanced budget amendment, and the Read the Bills Act, in addition to the widespread reduction of federal spending and taxation. He has gained prominence for his independent positions on many political issues, often clashing with both Republicans and Democrats.

Good Faith Collaboration: The Culture of Wikipedia is a 2010 book by Joseph M. Reagle Jr. (a Fellow at the Berkman Center for Internet and Society at Harvard Law School), published by MIT Press. The foreword is by Lawrence Lessig.

Good Faith Collaboration is based on Reagle's PhD dissertation. The book is a study of the history of Wikipedia, its real life and theoretical precursors, and the culture which has developed around it. Reagle explores the history of collaboration, touching on the methods of the Quakers, the World Brain envisaged by H. G. Wells and Paul Otlet's Universal Repository.

The book received a positive review from Cory Doctorow, who said that Reagle "offers a compelling case that Wikipedia's most fascinating and unprecedented aspect isn't the encyclopedia itself – rather, it's the collaborative culture that underpins it: brawling, self-reflexive, funny, serious, and full-tilt committed to the project."

In August 2011, Reagle was a keynote speaker at the Wikimania conference in Haifa, Israel. In September 2011 the Web edition of the book was released under a Creative Commons license.

"Choose the right" is a saying or motto among members of The Church of Jesus Christ of Latter-day Saints (LDS Church) that is taught to children and used by members of the church as a reminder to act righteously. The phrase is taken from an LDS hymn which has that title.

The letters CTR, a reference to this phrase, are incorporated into a shield logo designed by Helen Alldredge, a Primary General Board member in the 1960s. In 1970, a church committee headed by Naomi W. Randall recommended that the shield be incorporated into official church material. Since then, both the phrase and symbol have been used in religious educational materials for LDS youth of Primary age. The symbol is also used in LDS culture by members of all ages, both as a reminder of the motto, as well as an indicator of religious affiliation. The CTR initials, displayed on the shield and in other forms, can be seen mainly on CTR rings as well as other types of jewelry, tee shirts, bookmarks and stationery.

According to the US Patent and Trademark Office, the LDS Church's stylized "CTR" abbreviation and shield with the CTR symbol are trademarked for use on finger ring jewelry by Intellectual Reserve. The phrase "Choose the Right," however, is not trademarked in the United States and may be used by anyone for commercial purposes.^{[citation needed]}
