CMS feature list/ usergroup permissions
 

Where can I find an overview of what the CMS can do?
I don't want to plough through a whole manual at this stage. I just want a Features list.

Searching on CMS I get
The following words are either very common, too long, or too short and were not included in your search:
cms
Similarly VB CMS

One area I really want to know about is Usergroup permissions to view sections, and items on the menu, and widgets.
Also I would want to override attempts to go straight to any other area first - not allowed to bypass the CMS front page.
Essentially a way to build a Personal Entry page.

The whole Search on here has been so radically cut down and simplified it's a wreck - I used to be able to select a forum or forum category to search.
Is this going to be put back?
