Where is RokACL at this point in time?
It was my understanding for a very long time that we'd see better ACL in 1.5. I've been a Joomla since the beginning. I now have a project that will REQUIRE better and more granular access control and sadly, my beloved Joomla is simply not up to the task. In fact I am getting better access control for communication and files distribution from Simple Machines Forum than I am from Joomla. That doesn't work well for web content though... only files.
I am anxious to get this back on Joomla. In its current state as a CMS, Joomla has this one sticky point. the only thing you can actually MANAGE is who is able to WRITE or submit content. You have VERY little control over to whom you DELIVER or display content. (Public and Registered are simply not enough)
I am hopeful that RokACL will solve this and I look forward to seeing it. Right now the JXtended site appears to be place holder.
thank you, Andrew, for working on this. I am certain that when ready, it will blow peoples' socks off.

It will surely fill a need that has been promised for quite a while and YOUR involvement just gives me a much higher level of confidence as to HOW it will be done.
