Keeper-class cutter

The United States Coast Guard commissioned a new Keeper class of coastal buoy tenders in the 1990s that are 175 feet (53 m) in length and named after lighthouse keepers.

Keeper-class cutters serve the Coast Guard in a variety of missions and are tasked with maintaining aids to navigation (ATON), search and rescue (SAR), law enforcement (LE), migrant interdiction, marine safety inspections, environmental protection and natural resources management. Keeper-class cutters are also used for light ice breaking operations.

These vessels are 175' long and replaced the WWII era 180', 157' and 133' tenders. The new class of buoy tender cut crew size from 50, 35 and 26, respectively, to 25 saving the already cash strapped Coast Guard financial and personnel resources.

Keeper-class cutters were built by Marinette Marine of Marinette WI.

Keeper-class cutters are equipped with mechanical Z-drive azimuth thruster propulsion units instead of the standard propeller and rudder configuration. These mechanical drives are designed to independently rotate 360 degrees. Combined with a thruster in the bow, they enable Keeper-class tenders to dynamically maneuver in a variety of sea states. This creates an extremely maneuverable platform which, when combined with modern navigation aids such as GPS, DPS, and ECDIS to allow the Cutter to maintain static positions. This allows the cutter to precisely place an aid to navigation (ATON).

Messenger Plus!

Messenger Plus! (formerly known as Messenger Plus! Live, commonly abbreviated MsgPlus, Plus!, or incorrectly as MSN Plus) is an adware add-on for Windows Live Messenger and Skype. The software provides additional functionality to Microsoft's Instant messaging client, Windows Live Messenger, by adding its own controls to the main interface. These controls affect Messenger's behaviour and appearance, often through additional dialog boxes.

The add-on was first released in May 2001 under the name "The Messenger Plus! Extension" for MSN Messenger and Windows Messenger. It later changed its name to "Messenger Plus!" and then, for the release of the new Windows Live Messenger client, "Messenger Plus! Live" was chosen. In 2011 the name was changed back to "Messenger Plus!" again. It has become one of the most widely used add-ons for Microsoft's IM clients, citing over 62 million users as of February 2010.

Volunteers from the Messenger Plus! community around the world develop skins and scripts for submission into the database of the website for the software.
