Gina...are you honestly going to sit there and say that it's okay for multiple providers to access each other's accounts once they're set up? I know you're trying to stay out of things here, because of the side you have taken, but are you honestly going to let the hobbyists who use your site believe that it's okay for them to never know who they're talking to when they communicate with someone on your website?
It honestly drives a lot of hobbyists here nuts that they don't know who the pimps, agencies, and "helpers" are when they communicate...you have a mechanism in place for the first two, but seem to be actively ignoring the last. Is that true?
