I'm not sure Bud. Are you blocked from the forums all together or just the private section?  If it is just the private section, that is standard practice for clans once you quit.  If it is the forums all together, then I could only figure that it was an error. If that is the case, I will tell them and I would gather that they would give you back access to the forums.  Also, maybe you need to log in as Bloodclot and not [TA] Bloodclot.  They may have changed your name when you quit.  Hope this was a help, let me know. :P
