As you may notice with other "Finer" wikis, they lock pages.
Locking a page mean it is cemented into the wiki, so only admins/bureocrats can edit it.
Locking pages will stop vandalism on popular pages/rules and guideline pages.
Locking pages is a winning stragegy!
So admins, get doing it. As us "Lower" users don't really have magic wiki-wide changing skills... Yet.
