Just the other day I was thinking how cool it would be if one of those And1 streetballers put themselves through the hoop after a dunk. I question whether this video is doctored, but it appears to be legit.
I play at redhotpawn.com. You play it correspondence style, rather than having to be over the board at the same time. Nice clean interface, lots of features if you become a paid member but still a good site for free users.
