I'm already on that Discord. I didn't realise this adventure was made by the same person that did Mausritter itself! :) I guess paying for this is a good way to donate for such an excellent (and free) system.
I know how helpful and active you are over on your Discord server, as I've seen it myself, but there are a few questions here from other people who look like they've bought the product, are seeking help, and didn't know to ask on Discord :)
