Hi, I'm back.
I had just spent hours with the permissions. It is truely a worst nightmare than previous phpBB and SMF. I think I got most of them just fine, but will have to recheck thru them all to be sure.
In the GCP >>> STYLES >>> Templates, which option do I choose to edit the width of the entire template? Right now, it is blown way too big, from side to side. I would like to skim the width. Which specific codes line in a specific option dropdown?
