Since this forum is the best, I want an alternative hang-out to read a little news and pick up a few tips about sound design, production techniques, reviews of VSTs etc.

nice thread
foem (big forum with monthly remix competition of well-known techno acts)
mnml.nl (good forum)
for germans:
synthesizer forum (big, very mature)

If he wants maturity I would advise to avoid Dogs On Acid and Blackout Audio with a bargepole.
