I like to start off by expressing my gratitude at the Roll20 team for working tirelessly during the pandemic. One of the problems that I've began to encounter on Roll20 is the lack of feedback system. Roll20 does not have ways that allow players to leave a feedback about GMs/campaigns/modules. This presents problems to both paid and free games, but it affects the former more. There are a lot of games on Roll20 that charge 15+ USD per session per person outright prior to the first session. This is not cheap, but players don't have means to see if the GM is offering quality game that is worth the fee. On top of that, some shady GMs cheat players out of their money. Since it would be pretty hard to force GMs to make first session free, I propose some kind of feedback forum. This way, GMs can have a feedback threads where players who've been in their games can leave comments. This benefits both the GMs and players. Players can see what they are paying for/joining, and GMs can show others their credentials.
