Hey Liam, well, there are two things to be done here. If you want to rename a group - I'll interpret that as changing the little tag that appears on a user's profile, like "ADMIN" on my profile - you would edit Mediawiki system messages, such as Mediawiki:User-identity-box-group-sysop, on your wiki... for a full list of groups, you can see this page on my wiki, and try editing the equivalent pages on yours.

For even more control, you might see c:dev:UserTags.

If you want instead to add a group, then you will have to appeal to Staff at Special:Contact about the group to be added. Tell them what the group should be named, and what special abilities it should have (Special:ListGroupRights is a list of rights).

Feel free to continue this thread if you need further help with any of this - but in the future, it's probably better to ask these questions on Special:Chat or Special:Forum so the community can answer.
