The Davis Wiki has a few administrators. Admins can lock pages to prevent and help resolve edit wars. Admins can also ban users, which they most of the time will do to those who spam or initiate repeated vandalism against the Wiki.
The Administrators are:
All non-trivial administrative actions should be taken with community consensus.
I would recommend that there be some regular, periodic (rather than on-demand) forum for real time discussion among admins with the majority or all participating. I think it would help with keeping admin philosophies homogeneous (and thus evenhanded) and also elastic over time. I know I've pondered about a few things (ethically), and I'd be curious as to what other people's take on the same questions would be. I'd imagine it would be best to figure out after we add admins. — jw
That's what I meant by "elastic over time"... that new ideas are discussed to improve things and also to change over time as the Wiki scales up. — jw
Wouldn't it be better if admin philosophies were not homogenous? After all, the wiki is ever-changing. I'm not suggesting that there not be agreement between the admins, simply that new ideas will not be shot down automatically. —TusharRawat
