I just now searched for a specific game in the public games box, and typed in two RHP members names as player 1 and player 2. Since there were no games between them it, it told me Sorry, no users match that name, which made me think I had spelled one of the names wrong.
It would be a little bit better if the message said something like Sorry, no games between those two users are stored if the two users existed but had not played each other.
Sorry, just reread this and it's a pretty anal comment!
