Above is the newest version of XOOPS with no other modules installed. I used the center block to put my links into. (all these links are html visual presentation of what the XOOPS administration panel looks like for different operations) Nothing to be afraid of, it's very user friendly.
So step one is to install XOOPS 2.0.18
TO Install:
Xoops 2.0.18 zip file
I use Winzip, going to the very top file menu...
Select - ACTION | Select ALL | Extract
To your desktop
IF you don't get or haven't gotten this far... then let us know.
