Thumbwrumbler82, that's not true in the slightest.
If anyone would like to apply to receive adminship of an exisiting wiki, they'll need toapply for adoption via Adoption Requests. Please take a look at the posted guidelines there and then fill out an application if you meet those guidelines. Note, though, that you will need to be logged in to a Wikia account to request adoption (well, technically, you can request without being logged in, but your request will be denied).
Well, what Thumb said was true in that "A Wikia contributor"s, that is, IP users, cannot be promoted to admin. The person who posted this thread is free to log in to a Wikia account in order to pursue promotion, however.
