By inactive I mean not logged-in by the User.
I am asking this question because, I answered one or two OLD questions (3yrs old) hoping that he/she will try my solution and reply if not accepting. But I see nothing. No up-votes or down-votes or comments.
So, Is there any way I can know whether he/she is an active member?And Will the accounts get deleted (with their posts) if its not used for a long time?
