Forums ? No

No need of forums here, enough elsewhere:

Toy Town has some English language forum pages. (& many of the younger element of GEA or ex GEA (& some not so young) use those.
Risque Forum: A friend told me of a risque English language forum site in Munich - Probably several I guess. I'd list it if reminded of the address. Some sites use passwords & anonymity to begin with - Guess why ;-)
Lots of active forums in Munich if one reads German.
There's pedestrian puff pieces on forums on another site, promoted by pensioners trying to seize control of the GEA camouflaging their power grab with censored mail & propaganda about `reform'.
Enough choice, & forums only work while you have net access, whereas events mail lists & static web pages you can store & browse off line, on a train etc, so take your pick:
