I'm with Dr. Reef. I always forget one little thing that isnt worth making a new post. Or a spelling mistake always sucks. But... after reading a thread on reefcentral (I think) about DSB and one guy deleted all of his posts I got very frustrated. I could have learnt a lot, even though he had been shot down and made to beilve he was wrong, I find when it gets to things like that there is never really a flat out wrong side. Either way you can always learn.
