I believe this is also posted on the Wiki, although I'm not sure where.
Ads, if it isn't you should definitely add it!
If we do that people may start spamming to increase post count more than some already do.
I'll look for it in a little while and fight out if we should add it if it is not already there.
Well, considering that this person asked and we gave him the information makes it a little odd that we wouldn't make it general information to the public.
Also I am very opposed to withholding information from people just because they may spam posts to get a new picture under their avatar.
Please add it to the wiki if it isn't there. That would be ridiculous if you didn't.
