I'm pretty sure it'll be bcause Ross uses a shared computer offshore.  Believe me, the last thing you want is to hav auto log in on ANYTHING! 
  
I have heard (and seen) some horrific jokes played as someone has left email addresses in view or a computer logged in to some account or another. 
  
Spot on stew, dont want to log myself on unless i have too, if I forget to log myself off, you WILL see a barrage of posts proclaiming i like bum sex.  
  
Oh thanks Chesterfield
