First of all, you must be aware that Wikia can only do this once. That means that, once you've changed your username, you cannot change it again, no matter the reason. The process is irreversible. Make sure that the new name is exactly the way you want it.

You can follow this link to the page where you can request your account to be renamed. I highly recommend you read the help page on renaming your account before you actually go through with it.
