History.
The Ubuntu Forums were created by Ryan Troy in October 2004. The forums became a popular resource for Ubuntu and were deemed the Official Ubuntu Forums in November 2004. The forums hosting continued to be paid for by Ryan and the occasional donations of forum community members until March 2006, when Canonical offered to host the forums on its own servers. In June 2007, the forums' domain name, license, and assets were all transferred to Canonical, which now has sole ownership.
Role.
The primary function of The Ubuntu Forums is for Ubuntu support, but it also has a popular community area where other topics may be discussed.
Governance.
The Ubuntu Forums are governed by a moderation team made up of volunteers, often referred to as The Forum Staff. The Forum Staff have three ranks: Administrators, Super Moderators and Moderators. The Administrators serve on the Forum Council.
