The base of the CMS was coded from using RevCMS 1.9 how ever most of the code does not even look like it does with the original Rev Base.
And to the OP of the thread code your own THEME or buy one.
I'm saying that you could make the CMS load 2 separate databases.
It would provide better flexibility kind of a CMS database. like in the wow scene we have 1 auth 1 world and 1 site database.
