BitcoinTalk
The Bitcoin Forum is a message board where people interested in the technical details and the development of Bitcoin software can talk to each other. The forum also has places for people who are interested in bitcoin mining, in trading with bitcoin, and in the economics of Bitcoin.
The forum is administered by User:Sirius.
History
Before the creation of the current Bitcoin Forum, a SourceForge forum was used.
In July, 2011 the Bitcoin.org Forums were deprecated. The Forum link on the Bitcoin.org homepage now simply returns the google search results for the search terms "bitcoin forums".
