At what point does spamamge become a legitimate dwellar telling us about their new production?
I guess it depends on how much the poster has contributed in other areas (post count, time spent, and quality of posts), but also on whether the sale is mentioned once in an appropriate place, or shouted loudly in inappropriate threads.
On the latter criterion, I'm cool with this particular thread talking about his new book, but on the former criteria.... hmmmmmmmmm I'm not too sure.
EDIT: Just saw the other
thread about the same item from a slightly different angle.
Hmmmmmmmmmmm.

seems a bit excessive.
