As far as I remember, there was such a project year ago (successfully done). And it's still not in joomla, even 1.5. I really need flexible user rights management system for site I'm making and looking for.

My name is Alex and I'm from Russia (sorry for my English btw). I'm studying Computer science in Moscow State University. I know php,mySql,html... Hmmm... I've wrote some modules and mambots for my site, rewrote (changed a bit of functionality and removed some bugs) some 3dParty components.
Again sorry for my English, hope you're interested, Ataman
