[CentOS] RHEL7 beta discussions?

Where would be an appropriate place to get help with the quirks of
RHEL7 beta, particularly GUI usability issues?   Gnome3 won't work
under x2go, so I'm trying to use KDE but can't believe that anyone
actually uses borderless windows where you can't tell where you are
clicking near the edges,  grey-background terminals or the default
font set.  So there must be some other themes or a lot that I don't
know about it.
