Right now there's no way to delete groups actually.
What you can do is change the name to "group closed" and then delete all the other info (rules and what not) so that it's basically a blank group. Then simply "leave" the group. You may have to demote yourself from admin to regular member... I'm not 100% on that (as I haven't done it myself in a LONG time) but once you leave the group you should be good. Permalink
I think it's because a person who once got banned from Mocpages was in that group. You won't find him on the member page, but on the page where you can invite people, there is also a list showing the members in the group. If you find a buddy icon without a name, then remove it from the group. Then, you should be able to delete the group. This problem happened to me before, and that was the way I got it deleted.
