Anyone know a good free internet backgammon site?

I use to really like the internet backgammon on Windows XP. Tried Yahoo and GameZone or whatever it is MS recommends as a substitute. Not the same.

Any suggestions?

Thanks.

Or a good one where you have to pay?

Likely both the best and longest-running internet backgammon site is http://www.fibs.com/ . They have a ranking system, good tournament play, and many quite accomplished players. Any game site running since 1992 is bound to have a community!
