!Undertaker!: I'm not a big Checkers player or anything, but wanted to mention http://www.goldtoken.com as a possible site.
GoldToken has recently been choosen to become the official playing site of the American Checker Federation (ACF). So GT has been working hard making sure all rules are correct and everything - and has been adding checker variants. (Plus GT is the official game site for the New Zealand Draughts Association (NZDA) also)
But they have:
* Checkers * Armenian Checkers * 11 Man Ballot * Brazilian Checkers * Canadian Checkers * Czech Checkers 8 Man * Frisian Checkers * Giveaway Checkers * International Checkers * Italian Checkers * Pool Checkers * Restriction Checkers * Russian Checkers * Spanish Checkers * Turkish Checkers
I'm not sure how many of you have tried out that site, but it sounds like they are trying hard to bring their Checker games up to par - so it might be a place for Checker fans to check out.
