Yeah,
the best feature of the regional groups is to organize gatherings. However, in Europe as has been said, that's all covered.
In Germany and for Pentax, the following are the important forums:
-
DigitalFotoNetz.de :: Index
Pentax only, same size as pentaxforums.com (0.942186 million posts) and no, they do not run a million post contest.
-
DSLR-Forum
Not just Pentax, but 6.5 million posts while pentaxforums.com tries hard to reach 1 million. And Like Olympus, Pentax accounts to about 1/2 of Nikon and 1/4 of Canon traffic. Which makes it a Pentax forum about the size of pentaxforums.com too.
Most of the regional gatherings are organized by these forums and my city even has a local photo enthusiast meeting site (
Photo Walk Munich aka PWM).
However, a few events are pan European and using the Europa group of this forum would make sense.
One such example is the Photokina event in Cologne later this year.
