Infinity: The Quest for Earth Wiki/Administrators

Administrators can access additional tools on a wiki, which have special functions to the site. These include protecting and deleting articles, blocking vandals, reverting spam, editing the mediawiki interface and some other specialised abilities. Admins however, are not all powerful, and there is no hierarchy in wiki's, all users have the same amount of power. Decisions for the wiki are community, not admin-based. If you need help, admins are usually experienced enough to provide help if contacted, or could pass you on to someone who will know if they can't help. Finally, admins don't bite, so don't be afraid to talk to them, they are people too!
