I signed up for this place at work 6 years ago, and have been posting sporadically ever since.
No probs posting in work time at all, as long as the job gets done.
Work does block Facebook, Myspace, Youtube, hotmail etc, but the mighty MH forum has slipped through their net!
May have something to do with it's lack of popularity or traffic!
If history has taught us anything, it's that we've learnt nothing from it....
