You'll need a Discord account and one on Roll20-- both free.
https://support.discord.com/hc/en-us...etting-Started Discord is a combined text and voice channel, so working microphone and speakers are needed for this game

Once you have the Discord account, send me the name & number, and I can send you an invite.
I joined this game myself to learn some things about Roll2o, so I'm pretty newb with it.
