I have the Real players handbook and volo's guide but I don't get roll20... at all. do i have to re-buy my books online or can i just play? and what's up with the Grouping? is it like reddit where you start talking to others on threads/games? i'm already somewhat a noob to D&D in real life... i don't wanna go through a gauntlet of new s--t again (also uncertain if swearing is allowed so kinda have to bleep it out just to play it safe)
