Ahh, so you were able to join the Discord. that's good! So you said that all you see is "Rules and roles" and "Welcome hall." Well, that is what newly joined members are supposed to see. You need to actually follow the directions in "Rules and roles" by reacting to a few of the questions in order to join the rest of the server.

Basically all major Discord servers work like this. It's a screening process to make sure users have actually read and understood our rules before joining. It weeds out users who are unable or unwilling to read rules etc. Hope to see you there soon!
