How do i check how much rep do i have?
Click the settings page
If you've received rep, it should be the third box in the center of the page (I think)
For me, the first one says "clraik Referrals (0)," the second says "Subscribed Threads with New Posts (0):," and the third says "Latest Reputation Received (15 point(s) total)"
