Would it be possible to add feedback for local trades. Perhaps another rating icon (a car, perhaps)? That would let members know whether or not a specific user has been found to be a good trading partner, just as the star ratings work for mail trades.

Support; would be nice to know who is also pleasant and reliable in person, not just via postage. Just a simple icon added to reviews that were marked as 'Local'; also can be shown on profiles to notify users that a member is verified and verified locally.
