i just did a search on yahoo to get a better idea of what is going on. dud that sucks. actually something like this happened to me, i was using some ones name unknowingly and that person approached me rather threateningly. that was what made me begin my training, to protect myself. i think for you guys it's more of a "legal" matter. i'd check with lawyers, since from what i know this site has been the graphic designers site for a long time and worth looking into legally.
best regards, and i'll think of a name to put in the pot.
