On a user-page, in the info tab (which shows 'name', 'member for', 'seen' etc) add a line which shows the number of days elapsed since the user ased a question. To purpose of this is to raise user awareness about the frequency with which they ask questions, and hopefully increase the question contribution rate for IT Security.
Edit: I made this suggestion because currently (mid-2011) Area 51 shows that the IT Security 'questions per day' could use improvement. Area 51 shows the 'answer ratio' as excellent.
