The Thunderbird email client doesn't get half the attention that its big brother, the Firefox browser, gets, but the Mozilla Foundation has finally gotten around to lavishing some love on it, and <A HREF="http://www.eweek.com/article2/0,1759,2073562,00.asp?kc=EWRSS03119TX1K0000594">the first beta of version 2</A> is now out. If you think there's nothing more that can be added to an email client--except for the fabled seek-out-and-destroy-spam option--prepare to be pleasantly surprised. The new Thunderbird comes with numerous new features.
