I've been meaning to post this for a few days, thanks Leslie for the reminder.
The
Internet Scrabble Club is a site run out of Romania, of all places, that is amazing (in my opinion). It's geared toward the serious Scrabble player, and supports several offical dictionaries as well as many play parameters. It applies the NSA's rating algorithm and does a nice job of matching players with others at skill levels they would like to play.
It is a java applet that should work on all browsers. At its heart it's a command line interface (like the old MarlDOOM, anyone remember thatr?), but the java applet really takes care of most everything (drag and drop, graphics, etc.).
I'm
TPierzina there. I've been on most nights, I'd love to hook up with someone.
Also, games.com has a decent free Scrabble game. It also rates players but its features are nowhere near as robust as ISC.
I tried Networds, over IRC or ICQ or whatever, seemed like a whole lot of messing around for very little payoff--especially when compared to the other options out there.
