Well if you're in the mood for board games that you can play by e-mail (turn-based) or even live, I'd recommend
GoldToken.com.

They have a version of Scrabble called
Grabble as well as other games such as Chess, Checkers, Four In a Row, BattleShip, Trax, Dominoes, Rock Paper Scissors, Yahtzee and more.
GoldToken is the official home and playing site of the:
* Game Federation Association with the The Game Federation Association Club
* American Checker Federation with the The ACF Club
* New Zealand Draughts Association with the The NZDA Club
* World Pente Federation with the The World Pente Federation Club
* GOAMA
GoldToken is also home and playing site of the:
* International Chess Federation
* Kentucky Chess Association
* The American Backgammon Association
* The Chinese Go Association
* Welsh Draughts Association
* The International Backgammon Federation
I haven't really used GoldToken.com in a few years but I enjoyed it while I was there.
Full Disclosure: I am one of the co-founders of the website, my brother is the other. I personally haven't done much for the site since about 2002 and
I don't gain anything for telling you folks about it. My brother doesn't get anything either, as it's now owned and operated by another person.
