It's fine to use Discord for quick questions, but the general info on a character/system mechanics should be archived. No one is going to want to keep answering the same question over and over. For instance: http://ki.infil.net/
This makes things so much easier and people will have less of a reason to ask basic questions if all general info is put in an organized place. That site exist, but they may still use Discord for personal communication. Most of the other fighters on the market has their info scattered around on 6-7 sites/programs. A new player is not going to jump through hoops just to learn general info.
