You get blue stars as you reach certain post plateus. The first set of stars is a blue that looks frazzeled at the bottom. Whn you have posted enough to get like five stars you start over with ONE solid blue star. So on and so forth.......

Besides the stars though:

I'm still waiting to see if anyone will EVER get as many of those green markers under their stats as HaRRo has.

"HaRRo is truly awesome to behold" LOL!!!
