Yep, as in the good old days. Here's a thread where you post the story behind your avatar. Why do you use it? Are you really as sexy as your avatar? Etc, etc.
I'm rather boring*. My avatar is me, quite frankly. I don't have such a hat, and my sunglasses are way cooler, but apart from that, that's me.
(the sunglasses and hat where borrowed)
*for a given value of boring. The value in this case is, of course, "cool". Or possibly "sexy".
