When Citizendium started, experts were given a special status: they were allowed to "approve" articles and were able to decide who is right when there are conflicts over the content in the encyclopedia. As of 2020, the former "experts" policy is in limbo, as the membership of the wiki is too small to implement it and because it was deemed not effective. All writers are treated as equal.
Citizendium is now a small community. In early 2022, it had around ten contributors making at least one edit a month. The managing editors in 2022 are Pat Palmer and John Stephenson.
