Everyone with the exception of Elcentcom is making a valid point. He obviously hasn't looked deep enough into the RC. There are still many issues to be looked at.

We have been waiting a long time for this RC but it is only that...an RC - Release Candidate. It should not really be used on a live site, hence the word candidate.

I agree that the menus are a little on the OTT side but there are ways of keeping them simple.

You can start by simply removing the member menu. Go to the admin side see more of your site then:

Settings>Advanced Settings>Variables

Then you can simply uncheck "Enable member menu" which will start to make the page look less hectic.
