I just noticed this part: " Powered by clPortal 2.00.00" , guess I wasn't paying attention. If you're going to rebrand it I do request you indicate it is based on mojoportal rather than listing me directly. Usually a copyright notice on the bottom of the web site is about the web content not the software, so normally it would be copyright by content author.
A "Powered By" link is not required at all, but if you put one that says powered by something other than mojoportal you should indicate its based on mojoportal.
Best,
Joe
