Slitherine

Sorry if I missed this somewhere, but I had a great match with another player on iPad and we messaged about another game during the match. Unfortunately we did not exchange emails so we could coordinate the next match and now the previous match ended and I don't know how to find him. I looked for the name he uses on the iPad H2H, but can't find it on the forum - he may not be registered on the forum. Is there somewhere you can contact players using the name showing up on the iPad? Thx
