Inherited an CI project and am pretty lost with it.

@php_rocs

Yeah, you're absolutely right. Let's see what the people paying the bills think.. I've already made my case about running 10+ years old Joomla in production and this falls into the same category.

About the phpgacl.. You see any reason why they would have gone with that rather than CI's built in access controls?

Cheers,
