There is a great new service called CheckMyMate.org. The service provides a way of screening prospective sexual partners for STD's. Here's a quote from their website:

Our members' STD test results are sent to us from a doctor's office or lab. We create an anonymous online STD report, identified by a Member ID and containing status (Positive, Negative, or Not Tested) for 9 common STD's. Members control who can see their STD reports by issuing Permissions.

This service should be extremely useful for providers who will now have a way of sharing their STD status with clients, and vice versa.
