I received the trial accounts from Oracle to test run Beehive.
First impression - I am not very impressed. I'm confused, in fact.
The UI was not intuitive enough and there are numerous pop-ups when I clicked on the drop-down menu. I was expecting a seamless integrated UI. (May it's just me. I hate pop-ups)
By the way, the WebMail provided by Beehive is a Zimbra wrap.
I'm still trying to figure out the backend - Oracle Beehive Services. Oracle isn't telling much about how the core is been architected. I'll need to spend more effort discovering by myself.
