Are there any other national/international paddling boards, especially
for general paddling, besides rbp, BoaterTalk and Paddling.net?

Sure, many clubs and groups have their own local forums. Soulboater.com
(in German) and the UK rivers guidebook forum come to mind, but on a
smaller scale there are a bazillion more.

Sometimes the paddlers meet in a forum that isn't exclusively about
paddling, de.rec.outdoors for example.
