Not sure if it's been mentioned before, but I just noticed it.
If you receive a PM, then the "Private Messages: Unread 0, Total 132." part of the user block on the right disappears. Only way to get to your inbox is by going to your control panel.
Also I just noticed, I have 4 benchmarks that I've done on the same system. (4 different programs) yet it still only says Benchmarks: 2 under my name.
I fixed the private messages so it displays and also highlights in red.
It shows 4 under your name now. The counters update every time an admin checks off scores, so new benchmarks added won't show until there checked.
