Astromart "Message Inbox" inquires

I occaisionally receive inquires on my Astromart adds through my "Message Inbox" and not through the add, itself. I've agreed to either consumate a deal on several occaisions, but then never hear back from the individuals. Since it is not possible to rate the person through the email, they have no accountability. I was thinking of waiting until they post an add of their own and then rate them. After all the rating system is on the individual and not the product. I think it's only fair to keep other Astromarters informed of a person who does not deal with good character. Thoughts???

Ask them to respond through your ad before you tell them you agree to a deal. Then you can rate them. Just say that you will not accept offers through private message for this reason. If they don't like, too bad.
