I definitely think that wearing the clan tag is really important.  I don't think we should nessecarily remove his clan tag, just warn him.  THen again, if it's really been that many times, probably should be removed.  I mean, it's not hard to wear the clan tag!

I don't really see why he doesn't wear it.  If he's just too lazy to, then I think it should be removed.  Actually, there's no reason he shouldn't wear it.  So I think one last warning, this time like an official one.  Removing a clan tag is a pretty big deal, I think.  So if he really wants to be a part of the clan, then we'll see if he starts to wear it again.  If not, remove it.
