Sure but then you have to track down each and every person who put it up there to ask. If they're completely inactive, that might be tricky. Sounds like a lot of work.
Plus, it might have to be done anyway, as (hopefully) more and more clans may start to appear.
edit: Oh I think I get what you are saying. You mean remove the initial 3-4 posts in this thread? I suppose that's an option, but then Sunderland doesn't officially own those posts, if you know what I mean? Wouldn't he just be editing in and out of other peoples posts?
