So, we need 100 posts for the Blue Building, is there any way to check how many posts you're currently at?

Hover over your username and it will tell you.

Oh, Thank you so much! Hahaha! That was easy...

Feel sorta bad how obvious it was.

Nah don't be, it's easy to miss. Also there's a widget for your profile, the extra user info I belive, it also shows your post count.

You can also check it in your achievements under forums 😊
