Sue Gardner (born May 11, 1967) is the current executive director of the Wikimedia Foundation in San Francisco, and previous director of the Canadian Broadcasting Corporation's website and online news outlets.

Gardner grew up in Port Hope, Ontario, Canada, the daughter of an Anglican minister and school principal. She received a degree in journalism from Ryerson University. She began her career on Canadian Broadcasting Corporation (CBC) radio in 1990 on the program As It Happens, and worked for more than a decade as a producer, reporter and documentary-maker for CBC Radio current-affairs and for Newsworld International, focusing on pop culture and social issues.

In March 2006, she succeeded Claude Galipeau as Senior Director of the division of 150 new media staff developing CBC.ca, the CBC website and Internet platform.

In May 2007, Gardner resigned from CBC, and shortly thereafter began consulting for the Wikimedia Foundation as a special advisor on operations and governance.

In December 2007, she was hired as the Foundation's Executive Director. Over the next two years, she oversaw growth of the staff including the addition of a fundraising team, and an office move from Tampa to San Francisco.

An estate agent is a person or business that arranges the selling, renting or management of properties, and other buildings, in the United Kingdom and Ireland. An agent that specialises in renting is often called a letting or management agent. Estate agents are mainly engaged in the marketing of property available for sale and a solicitor or licensed conveyancer is used to prepare the legal documents. In Scotland, however, many solicitors also act as estate agents, a practice that is rare in England and Wales.

It is customary in the United Kingdom and in Ireland to refer to real estate or real property simply as property.

The estate agent remains the current title for the person responsible for the management of one group of privately owned, all or mostly tenanted, properties under one ownership. Alternative titles are Factor, Steward or Bailiff depending on the era, the region and the extent of the property concerned.

The term originally referred to a person responsible for managing a landed estate, while those engaged in the buying and selling of homes were "House Agents", and those selling land were "Land Agents". However, in the 20th century, "Estate Agent" started to be used as a generic term, perhaps because it was thought to sound more impressive. Estate agent is roughly synonymous in the United States with the term real estate broker.
