It all depends on certain rules enforced in them.
I have an eating disorder so I find it easy to talk to people I can relate too.
I think that these sorts of chat rooms/sites are generally good as long as you're not allowed to give 'tips' to anyone and that the people there aren't 'wanarexic' : people who want to be anorexic.
if the chat rooms are people who are generally anorexic/bulimic then there i don't find a problem.
