:D We now have a GigaMember
Uh, no. Assuming that we use the binary equivalents of the metric prefixes, a gigamember would be the 2^30th member. That would be member 1,073,741,824. What you are thinking of is the kilomember, or the 2^10th member (1024). Even then, I would argue that using the binary equivalents of metric prefixes is inappropriate in this case.
Well... IIRC, didn't ~tl put a better Completely Automated Public Turing test to tell Computers and Humans Apart in place? So therefore most, if not all, of the accounts now are created by humans, so the ones that don't post anything are probebly just lurkers. They probebly only created an account to get rid of that awful prosilver theme.
