Might be that you're fairly new around here.

The thread I posted yesterday is gone too and I'm most definitely not new. Mine was also within guidelines. Guess I'll have to PM a mod or something and see whats what.

Well, mostly, when you post a thread in the Suggestions section, it is inactive, unless a moderator goes through it and enables it. And when he/she does, the thread will be visible to the community. Might be so that a mod didn't go through it yet.

But since you claim it was there yesterday, it could be deleted due to it being already suggested.

There are some threads slipping through who don't follow the template and/or suggest a game already suggested previously.
