Composition of the Board of Trustees
The composition of the Wikimedia Foundation Board of Trustees is currently set by Article IV, section 3 of the Wikimedia Foundation bylaws, which establish that the Board should include three community-selected trustees, two trustees selected by Affiliates, one "Community Founder" seat held by Jimmy Wales, and four seats appointed by the rest of the board for "specific expertise". This format was set in 2008 (see announcement, resolution), before which there were a smaller number of members.
Proposals to change Board composition
In 2015, the Board held a consultation on the composition of the Board, during which several proposals were put forth.
