Slitherine

I received the email that it is now my turn to play but neither of my mirror matches show up.

Hi, just to check, you have logged into MP and clicked on the "My Games" tab in the MP lobby?

You should have 1 (or possibly 2 if your opponent has played his turn) games in the My Turn tab, and (if your opponent has not yet played a turn) 1 in the Enemy Turn tab.

Turns out I was using my fog2 game account to login and not my slitherine one.

Glad you managed to sort it out.
