What do you play?
I have played MMORPG's since the old days with text based MUDS, my favorite one being Dragon Realms from Simutronics.
Then things went awesome... Everquest. We took the text based mud and made it 3D on a grand scale. I played since the early days and would often wear a diaper while I was the healer for my groups.
Diapers were not only fun, but practical! As a healer I would be one of the major cogs keeping the group from dying, so having to say "afk, bio break" a lot really isn't a good idea. With diapers I can stay way longer.
Of course the youngsters here likely are more into World Of Warcraft. Wouldn't it be funny to have a diapered guild in WOW?
