Hopefully any new site keeps the high standards romhacking dot net upheld; it’s way too easy to make a hack that unintentionally breaks other things in a game.
Regarding Discord, its un-openness to the 'net at large is definitely a prominent issue. But another problem (based on my limited experience) is that its people just aren’t very friendly. It’s like a large portion of them are annoyed at having to interact with other people. I don’t know why that is or even if it’s true, but that’s the feeling I got from it.
