Asking because I am trying to gain access to the BB.

I'm guessing you mean the forum posts and not points.

It shows up on your profile where it says "Forum Posts: 7 - Recent Posts - Recent Topics" the number there is how many times you've posted.

You can also hover over your username and it has the number next to the little chat bubble icon there as well. The number below that next to the trophy is how many achievements you've earned.

I think you mean posts?

Forum Points are a currency that you can spend in the Forum Shop. They're also called Forum Tickets on the currency page, but when you see them in your events, they're called points. (Not really sure why the discrepancy; never even noticed it before now.)

100 Forum Posts, on the other hand, are one of the requirements of gaining access to the Blue Building. You can view them by:

1. Hovering over your username and looking at the number just under your status and right next to a speech bubble. This is your number of forum posts.
2. Going to your user profile and looking at the third line under the "extra userinfo" section. There's also links to your posts and topics here.

Right now it looks like you have 7. :)

Edit: Whoops, beat me to it!
