¶ A Polite Request
Please don’t post links to or screenshots of the product(s) in public forums such on sites such as Twitter, Facebook, Reddit, YouTube, etc., or on official, branded, public Discord servers (e.g. those belonging to D&D Beyond or Roll20). If you stream your games, do what you can to hide the product(s) from view.
Although we love sharing and watching others benefit from our work, it brings a cost onto us beyond simple development: support. We’re just a few volunteers working for you in our free time, so it’s very easy for us to get overwhelmed with basic questions. Luckily, if you’re reading this, we already have great trust you won’t be one of those people—thank you!
Rule of thumb: Unless you’re willing to provide lifetime support to a person, don’t share the tools with them!
