Well, i.m.o. Playmoboard is still worth visiting, though it isn't as wonderful as it once used to be. Several years ago, there were much more interesting posts and many more active members, from all over the world.
Sadly, there has been a big discussion which lead to people leaving or being banned. Others just went quiet and stopped posting. New members have joined since then, but I have the impression most of them are from the US and so the board seems less international.
Playmofriends was founded by people who are or were members of Playmoboard.
