Sorry mate. Misunderstood you there for a second.
I see why you would want to delete stuff in the particular case you are referring to, however, I don't think it's good if regular posters can delete threads. That way, if someone starts a thread and gives his opinion, and someone happens to disagree with him, the thread starter could always just delete the thread, should the discussion 'turn against him'. Which, I think, would defeat the purpose of forums like these.
Just my opinion.
Mate, I hope you pull that series thing off, it'll be good.
