Beginner quality of life questions

Some quality of life questions from someone playing for the first time since VF4: Evo:

- Is there any way to reset Shun's drink count in training mode? - Is there any way to block certain players with bad connections? - Is there any way to change your screen name? - Is there a modern wiki or is virtuafighter.com still the go to? - Is there a respository of character guides (Shun in particular)? - Is there a main discord that people use these days? Link?

Thanks.
