I'll go first - I'm here at least once a day, sometimes 2 or 3 times. But I go through phases where I am logged out but checking in compulsively - like several times an hour. Oh and if I have a deadline to meet - like a paper to write or a project to complete, it might be gazillion times!! Other times, I feel like I have to step away completely for awhile (especially if I'm on a shopping ban!).
