Here is my question, how does one limit access of a blog to just the users that are included into a user group?

***** Looks like there may have been a cache issue, after a reboot, the advanced user and user group tabs appeared. I will be testing with the new tabs. *****

Current Scenario:

One b2evo installation:

b2evolution version = 5.2.2-stable released on 02/21/15
MySQL version = 5.0.91
MySQL UTF-8 support = Yes
PHP version = 5.3.29-pl0-gentoo

--> Two public blogs
--> Five blogs that are set to the membership level

I would like to limit access to each one of the membership level blogs by associating access by "User Group"

Can I do this with one installation of b2evolution?

I haven't found where one can set the security access to a "user group" to a blog, even though I believe the documentation says one can.

Can 'User Groups' restrict access to membership level blogs?

If so, where do I set the blog security to allow only access by the specific 'User Group"?

Or do I have a wrong impression of blog security access?
