You set up a PBEM (play by email/forum - it’s an option on TripleA, on the right hand side) game. You need your opponent’s email address. And the games get saved/posted to the forum. Your opponent gets dice rolls emailed to them. Garg has a great TripleA setup tutorial posted. Maybe he can link you to the thread; it got me started easy peasy.
Thank you, that would be awsome
