If you need permission to edit a wiki page then you probably found a protected page only editable by Administrators or logged in users. If the latter is the case, log in or create an account. If the former is the case, go to [wiki].wikia.com/wiki/Special:ListUsers and locate the Administrators. You should go to their message wall and ask one of the following:
- Can I have a promotion? (Doesn't usually work)
- Can you lower the protection on ... page?
- Can you edit ... page for me?
