A bit of clarification here. All three of us are administrators, which means we have almost all of the available tools for editing and maintenance. In the capacity of an admin, we can try to guide the members of the wiki towards common goals, settle disputes (as fairly and impartially as we can), set policies (ideally with approval first instead of being arbitrary or a rude surprise), clean up messes created by vandals and trolls, and set blocks. We can grant/remove Threadmoderator rights to people, which means they can do maintenance here in the Discussions area, such as deleting messages reported by other users.
What we can't do is grant the rest of the user rights: content-moderator (editing/maintaining/deleting pages and files on the main part of the wiki), rollback so a group of edits by the same person can be undone in one click, and make other users admins or bureaucrats. It takes a bureaucrat to do it.
The two bureaucrats for this wiki are GethN7 and Junior admin, who got 'crat and admin rights when he created the wiki on May 19, 2014 and then he left after making that one edit. Junior probably won't ever be back. If we had a case where none of the wiki's 'crats would be coming back, we'd go through the adoption process so someone could become a bureaucrat.
We don't know if that applies here, so what we really are doing is preparing to ask Fandom for a special promotion to receive bureaucrat rights. Since a 'crat has the most rights on a wiki except for Fandom staff and volunteers from the Council, SOAP and other teams, the person you vote for needs to be trustworthy and won't promote or demote people without just cause.
Two examples of abusing 'crat rights I witnessed:
The bureaucrat of a wiki started giving 'crat and admin rights to their friends. Over the next month or so, they promoted and demoted each other like it was a game. I lost track trying to figure out who was an admin there because it changed multiple times a day.
A person tricked a bureaucrat into giving them 'crat rights. They used those to go on a vandalism spree and promoted several of their sockpuppet accounts to bureaucrat. It took getting Fandom involved to shut the vandal down.
For simplicity, let's keep the voting for one person. After they're bureaucrat, they'll be able to handle future user rights requests and petitions for demotion. They can start a new discussion about whether one or both of the other two candidates should also become a bureaucrat. It's generally a good idea for a wiki to have two bureaucrats to avoid situations like we find ourselves in right now: no one available to handle all user rights requests.
Update: Geth posted elsewhere that the appeal of the block was denied, so we are officially at a point where we have to submit a request to Fandom for bureaucrat rights.
