I kind of botched my first attempt to play on this forum but I was hoping for a game that either starts or has an opening.
I have some experience with ArM5, but lost my pen and paper troupe because I had to move.
I don't run games online (as a professional engineer, I'm naturally a computer-shy luddite in my personal life), so I can't be directly helpful, but try checking on the Ars Magica Discord server - I have seen games advertised there far more often than here, though never played in one.
Edit: post in players-lfg, or look in gm-free to find a game.
Would you be interested in a game played on Discord?
