Just popped back over...
Nice work!
I like how you tied the sessions in also
I spent some time chatting with a friend of mine who has agreed to look it over. Basically I am trying to accomplish what you have done above but allow for each of the multi-sites to have their own distinct permission/group list.
For Example Ted could be a:
Super Admin on Site A
Registered User on Site B
Author on Site C
I really appreciate the help MMX
I noticed the configuration.php would write out the addional changes also last night. I just resigned to editing it myself and uploading it.
