I can most definately understand that, and that is very frustrating!! But I think that's just kind of the risk that you take when ever you sign up to do any kind of exchange, be it with people you don't see like here or even the ones you do, in an office or neighborhood. It doesn't make it acceptable, but that's just how some people are I guess. Sigh!!!
I am fairly new, and was hesitant to want to participate---though I promise to participate properly-- but what is Elfster that other people are talking about?
