If hover over my username, it shows my achievements, but it won't when I post on the forum. Also, it won't give me any other nickname option than the one I currently have, when I have way more that should show up.

I don't know if I should've filed a ticket, but this seemed like the right place to post this.

Just FYI, the name on your hover is found under Personal > User Dashboard > Basic Options It's the name :)
