Adoption is a process whereby a user on a wiki with no active bureaucrats makes an appeal to Wikia Staff. A member of Staff will check their contributions and a few other requirements, and possibly grant the user administrator rights, and also bureaucrat rights (the latter meaning they have the capacity to make other users on the wiki into administrators and bureaucrats).

You should make an adoption request here. Having done that, keep editing the wiki (important!) and after maybe a week you should get a response.
