[insidious]

It'd be cool if we could @Otaku, although what if there's a member named Otaku?

I feel as if this would be a problem.

It already is...

I'd assume it wouldn't be too much of a problem to rename those members to something like MemberName1 insted of MemberName (so Otaku1) especially if those members haven't been active in 2+ years.

After that it's a matter of adding groupnames to the "not available" list of usernames so that if someone registers for the site they can't choose a group name as their name.
