if it comes up in conversation and the person is not spamming, whats the diff? most of the people that post on the glyco forum are mannatechies. the ones posting links to their propoganda were censured. if someone wants to contact someone like doc77 and order something from him because thay can email him, that is in the course of doing curezone business, not their business. there is a big difference.
there is also a forum for selling things here at curezone, and i would encourage anyone with a personal business with health goodies to post their contact info there. if it generates enough business, the person can feel free to donate to curezone in appreciation, which i would also encourage anyway.
