It's a good idea but if i were you i'd just put together one big pdf manual starting with the basics of sound design working upto modular synthesis/hcm and the likes.
Include things like diagrams etc as i don't think a chatroom will suffice due to some people (no offence) just can't take it in what is being explained to them.
Iv'e been designing sounds since 1988 but unless i had the actual person sitting with me while i showed them the techniques i use to design sounds i don't see what they could possibly learn in the long run, however writing a manual with diagrams + explanations would probably be the better way forward but i wish you look on your venture and i hope it works out for you.
