Daily counter and options to extend

Hello! I'm trying to achieve something, but not sure for to do it... What I want is to have a fixed daily limit for all users set to 1h. That is no problem, since I set Max-Daily-Session for all users via group check. But sometimes I would like to extend that limit to 2 or more hours for certain users. I could set Max-Daily-Session for that certain user, but that setting would not get reset at the end of the way. I would have to run a cronjob to purge settings in sql... Is there a nicer/proper way of achieving that? Matej -- --- Matej Zerovnik
