I tried 3-4 extensions placed here. But I have to say that Remository is the best (in my opinion of course). It does everything what I need and the best way. Very good access control. And easy set-easy use.

I tried 4 the best popular PMS placed here. But I have to say that uddeIM is the best (in my opinion of course). It does everything what I need and is simple to set it. I have translated it to czech and have sent translation to developer´s page.
