Hi. I made a WoW Addon Discord. It's still a little bit of a work in progress here and there but I have a few addon devs. I wanted to make it to be a place to both teach players and ask questions. I thought I'd finally post it here.
Edit: The original link should work, but something is wrong with discord atm. For now, you need to manually join and paste in the link yourself. (See pictures below.)

If you're an addon dev just PM me or something and I'll put you as an Addon Dev role. I generally try to ask what projects you've worked on just to make sure.
