I have been using Genome Mate since January. It's an excellent tool for storing your autosomal matches from the various sources.
Becky, the developer, is very responsive to requests for additional features. She is also very helpful with any issues that arise.
I've been recommending it to my contacts that are interested in mapping their chromosomes. I also think that it would be a great tool for adoptees to collect their matches and see possible trends.
