We tried moving my Star Trek Adventures campaign to Discord/Roll 20, but I'm just not up with all the bells and whistles. Even when someone took over as GM, I found the experience lacking. So ultimately I ended up dropping out of my own campaign (after handing it off to one of the players to run).
These days, sadly, the only roleplaying I get is on RPOL.net, a play-by-post forum. It's fun, but of course the nature of play-by-post means it's slow, and lacking in many of the fun interactions of playing at a table with live people.
There, I'm currently running Star Trek Adventures (a different campaign than my old tabletop one, set during the "Wrath of Khan" era), and Mutant Future (using elements of 1e Gamma World).
I'm also playing in a 1st edition AD&D game, a B/X D&D game, an ALIENS game, and a Call of Cthulu 7e game. If that seems like a lot... they all move very slowly.
