If you’re playing a word game, and you don’t have a dictionary handy (but do have access to the web), you can find out whether a word is likely to be legal by typing it into the box at What’s the good word? Yes, it’s ugly, but it’s usable from a phone (and I’m not Mr Web Designer anyway). I may build a wml version to make it a little phone-friendlier, but I don’t expect to make the html version any prettier.
