What about Evolution?
I dunno about all of the rest of the ppl on the net but I know of one of the HUGEST PROJECTS TO THE OPEN SOURCE COMMUNITY.
I am personally anxiously waiting for even an ALPHA to play with just 'cause it's such a cool concept!!!!
"Evolution is the Helix Code mailer, calendar, and contact
manager. But more than that, it is the next step forward in
GNOME applications. The three tools will be tightly integrated with one another and act as a seamless personal
information-management tool. Evolution will be highly
scriptable and it will be possible to use it to solve a huge variety of information-sharing problems."
Definetly a company worth investing in!
ps: I Love What They've Done To Gnome!!!!!!
