I apologize if the title was not the best. I fully understand that wikis are for everyone to edit in general but there are cases where the topic is limited in content such as when new information is released (ice age wiki, other smaller ones). other times it involves how long could a wiki be sustained in the current state.
would it ever be acceptable to have an exception to this rule if in the long run, there are both too many articles to keep track and the number of active editors are fewer than say 5 on a daily basis? an exception being locking articles once 'mostly finished'. even preventing wiki contributors does always not prevent them from doing the same with an account.
not sure if this is a good idea or not but perhaps VSTF should be given the ability to revert edits that are in violations of a wiki's policy and should only be used when requested by members of the wiki? it would help smaller wikis that don't always have admins logged in.
