I need to get into the Blue Building still and I have to have made 100 posts, but I have no way of knowing how many I've made because it doesn't count them anywhere, and I'd have to manually count them otherwise so I was wondering if there's a spot anywhere where you can see how many forum posts you have made

hover over your username right now in your post above me. The icon that looks like a comic book speech bubble has a number after it. You have made seventy one posts.

Hover over your username - it's listed next to the speech bubble. You've made 71 posts. c: The first post in a forum thread doesn't count, so this one won't have added any. I recommend the Games forum - I use it to get my forum points up.

Oh wow thanks guys I had no idea that was a post counter. Looks like I should probably be more active on forums then I'm usually just a lurker so that's probably why I haven't gotten many posts

you are welcome. The thingy just below it is an Achievement counter.
