There are several posters who when you type their names it appears as nudgescuffler.................u. m. m. m. m. happens to be one of them. I believe it signifies they are on the naughty step.
You'll wait a long time I think murraymints, the nudescuffler debarcle has got many people's hackles up including mine but the Ed seems to think it's a super idea, so it's stayed.
