(Try not to laugh)

Exactly how do I use Zimbra? I installed it, and didn't see any errors. Not sure how to run it now. It installs in /opt/zimbra (I'm on FC4), but when I go there, all that I am able to run are command line 'daemons' and such.

I'm assuming I'm in the right place here. Zimbra is something like Thunderbird, right? Is that only in the "Network Trial Version"? I have the open source one, and am not able to run it.

Someone please explain.

I apologize for my naïveté.
