There is a relatively (1+ year) new dutch beekeeping forum at imkerplatform[DOT]nl
The forum tries to reach modern and innovative beekeepers who want to discuss more than just the tradional items of beekeeping.
Keywords for imkerplatform.nl are: urban beekeeping, attracting new generation beekeepers, beekeeping in the bigger picture etc.
The forum's lead language is Dutch, but most visitors are capable of understanding english and german.
Thanks for reading,
