Hi William. Welcome to FG. Discord is an app that is used so the players and I can talk to one another using voice (www.discordapp.com). It can also be used to type messages to one another, although we would not do that in game. Typing messages would be used only in FG during game. After you launch, I recommend searching for and joining the Fantasy Grounds and Fantasy Grounds College servers in the discord search. Also, check out and watch the fantasy grounds tutorials on youtube (https://www.youtube.com/channel/UCmU...LMzAjnylWlIyyA). If you don't have a microphone, you'll need to pick one up. I recommend using a headset.
Do you have an idea what character class/race you'd like to play?
