I consider Playmofriends (PF) and Klickywelt (KW) as my "home-forums", though I write somewhat more overhere then on KW.
My English writing-skills are still a bit better then my German ones and so it is still a bit easier for me do discuss things in English.
I´m also registered on the international forum Tricorne-Jock (TJ) and the Spanish forum Playclicks (PC), but I don´t have enought time to check those on a regular basis, not to speak of participating there.
It´s been a long while since I vistited any dedicated French forum, it is just too much all together.
Concerning Laughing Giraffe (LG), I registered there as well after Playmoboard (PB) split up many years ago, but LG never got much traction.
I think it is good the major language-groups have / keep their own forum (not everyone speaks / understands multiple languages) so people can express themselves fluently in their mother-tongue (or a common language like f.e. English), but I wish the PCC had a better format so the ones who want to communicate internationally would have a common place to do so in an effective way.
