So I get that roll20 is a virtual board and all, but how does it work exactly? What can I do with it? I am trying to make my own RPG with a friend, just for fun and all, so mechanics wise it is unique. Will the program record health and other status that are used in our game? I really am not sure what I should ask here as I am new to the RPG world (parent's wont lemme play D&D, so that's why were making our own, as he does play that kinda stuff). Anything I should know about Roll20 would be greatly appricated ^_^
