Hmm only two games. I guess that's not bad if you're not trying to play against too many people at the same time, but that's kind of the point. I would suggest sending out the invite/challenge/whatever you want to call it a few hours, or maybe even a day, before the simul actually starts.
Also, since you have premium membership, you turn on the setting for multiple games. I don't have premium and I haven't tried chess.com's simul/multiple games thing, but from what I've seen I think lichess has a better system for simuls anyways.
Hello, today I will be hosting a Simultaneous exhibition at Lichess (because I don't know if you can do this on chess.com)
Join and play me?
