sorry - one last thing: international fields and times
Profile - name / city / country  = jamie toronto canada

so on everything i post or create it would say:

"Posted to C9 at 7pm  ( Your time 10pm)"  ...or something that shows the same thing

other posts would show:

"Posted to C9 at 7pm ( by _user_ at _timezone of country_)"

edit - it would be so great to see:
a) where everyone is from
b) if im talking to someone at 4pm here and its 2am there
