Where Is Former Challenge?

Is there a way to find out who it was the challenged me recently? I want to find out who that was, at least, because I want to send him or her a message. I might have tried to send him or her a message recently saying that the game was too short, but it might not have gone through if my message limit of 6 messages sent was reached before I sent him or her a message.

Also, I may want to challenge him or her soon with a longer time for our game.

If you have deleted the game, there will be no further record of it, sorry.

Russ,
I did not delete the game, but I guess my opponent did delete it.
