I've been customizing the webmail client, and I've added a LOT of functionaility and other miscellaneous options to it. Anyone with an e-mail account should check out the new options next time they log on.
Let me also just say that in general I'm not a fan of webmail clients. I've yet to find one with an interface I really care for, features all the options I expect in a good mail client, or that just plain doesn't suck. Squirrelmail (the webmail client used for LegRoom.net), though, is truly a great e-mail client that impresses even me. For those of you who don't know me well, that's quite an endorsement. :-) You can check it out for yourself at http://www.squirrelmail.org/. Enjoy!
