I set Discord up for everyone! Of course it's okay. It is located in Central US, so it should be pretty solid for everyone.Free Skype has a limit of 25.
Parkhyeyeon and JestersGhost both have Discord servers that should allow 100+ connections.
I'm an admin on Park's Discord, so if he is agreeable, I can run as host for the log-in event if he is not available.
I hope the time is good for me to join in also, and I will stream. I can also setup Discord to announce when others are streaming, so long as they link Twitch with their Discord.
