Welcome! We all come from different backgrounds. Personally I know just enough about coding to break things (reliably - ask Whisky!) but I am an experienced world creator. My current project is a labor of love as I re-create my old tabletop RPG world into the MUD world.
There is a Discord channel of sorts but I stopped participating in it almost six months ago. It was distracting me from working on my game.
I've found in a pinch that if I really need help I can log into TBA and Fizban is around to walk me through things. If you haven't gone through the builder tutorial in TBA yet I heartily encourage you to do so.
Give a shout when and if you get stuck, or an idea comes to mind but you don't know how to get it implemented in quite the right way!
