To reiterate:

To create a custom group on a wiki, you need to hold a discussion on it, and then ask Wikia Staff via Special:Contact/general. You need to be very specific on which rights the new user will have, so Staff knows precisely what to give to the group.

You do not have to paste any code anywhere.
