            Express Edition
            Express edition was launched and looks like the best open-source collaboration application that I have seen. Runs on Ubuntu

            This project seems to be dead
            There has been no progress since august 2006... Unfortunately a great project simply dies away..

            Zimbra has about 1/2 the functionality and is long-term way more expensive than OX (OX charges only for upgrades, zimbra uses a subscription-based model per-user/per-year). Both are good products, but I would suggest OX if you're looking long-term.

            Love it...
            Great project, I was amazed at the functionality of it. Hope word gets around soon, the developers deserve the credit. For a small or mid-sized company, this product alone has done wonders for our productivity without taking anything away in terms of training. Thanks guys!!

            Re: Great piece of software
            Full ACK. After having some problems with the installation (specially the ldap part) it is a smart running piece of software. You'll get a bunch of full featured modules with lots of options. I won't miss it! Thanks to the whole OX developers, as well to the community and keep on the good work.


            BTW: For those who have problems its worth to take a look to the forum, the wiki or the mailing lists which contains lots of informations about the installation, documentation and other misc stuff.
