Normally half of the board, 4 of the 8 members, are up for election each year for a two year term. If additional vacancies are present in the board, additional members will be elected to fill the remaining portion of vacated terms.
The Members of the X.Org Foundation are eligible to vote in elections. Membership is open to individuals who have contributed to the X Window System in some way, typically code, documentation or substantive public service.
Votes are collected via a web application on http://members.x.org/ during an announced period. Each voter provides a ranked list of their preferences among the nominated candidates. The results are then tallied using the simple Borda Count method.
For example, in an election with 6 candidates, the rankings are scored as follows:
Thus, refusing to rank someone denies them any points at all. Of course each rank can be assigned to at most one candidate.
Candidates with the highest point total are elected to the board until all available seats for two-year terms are taken. If any remaining seats are open to fill vacancies, the next highest scoring candidates are elected to those until they are all filled.
There is a limit of no more than two directors affiliated with the same company or institution. Once two seats are filled with affiliates of a given entity, all further candidates from that entity are skipped over in the ranked results list.
