Right, there's
threadID=28853 for this kind of ads. You open a new thread only if the game has some special rules players must know before joining.
But the reason why I "facepalmed" is mostly the second post. It made me think that *you* are in that Anon game because... who, outside the game, would have interest in posting that? (not that who's in should)
It also made me think that you opened this thread: a thing confirmed by your third post.
If you feel like you must tell everybody that a game you advertised is full, I suggest you a post like "all spots filled in gameID=xxxxx". This way your second post will be Anon too.

• Anonymous posts in forum
You can make an anonymous post in the forum (to search for players in an anon game for example) by linking to an anon game. If you link to the game in the subject line all posts are labeled as anon, if you link to an anon game in the post only this post is anon. Be careful, the mods still can see your real username, so don't misuse this feature.
