Too bad. My GM runs a RM game on Discord, and finding players familiar with RM is hard. The D&D/Pathfinder kids have no clue how deadly RM could be for people used to those games...
For new players I run a "RM Boot Camp" that allows them to spar with monsters and people to get used to the mechanics of combat and magic.
I use the same to teach any game and it is effective, as long as you walk them through at a pace they could follow...but...there are some players that I've met who just cannot do the math, and others who have no business playing RPGs...
