As I had done several times before I have removed all accounts which never loged in or did not log in for more than 9 months.
I think I'm going to short that period to 6 months at the end of of october and possible 3 months at the end of the year.
I'm easily to convince that 3 months are to short, OTOH I would like to read something realistic when I look at the user counter.
