SD&D has changed a few times... every few years there's been a disagreement over whether post counts should be accrued in various boards. Obviously the last 'review' deemed SD&D to not need post counts, or I simply forgot to change it!
Anyhow, in light of it actually being a serious board, and that online games does actually increase the user post count (which I did not know about), I have updated SD&D to count posts. Note that existing posts in that board will not be reflected for technical reasons (i.e. that 2S doesn't maintain all user posts on the forum so recounting would destroy the post counts of some people).
