My few visits suggested that the Polish and Spanish GM communities are the most active -- but that's just my quick (non-objective) observation.
You might have overlooked a lot of activity on the Dutch forum (
Nederlandse Game Maker Community) then, because it is
thriving, and viewing total message counts, seems to be larger than both of these two added up

Don't forget that Game Maker started out as a program created by a Dutch guy. I think that helped a lot. And we're in our 33rd (friendly but "official") competition already

Mainly, I'm curious how many GMC regulars are also members of these (or other) GameMaker community forums. Specifically, I mean GM forums that have been around a long while, and have +1000 members -- not small start-up forums (please...)
I started out on the Dutch forum before even finding this GMC here. In fact I have been a moderator since 2007 and just recently became administrator.
What feels really missing in GMC comparing to it's "russian colleagues" is threatening of "lameness" on side of newbies.
Both listed forums have pinned rule topics in 'novice question' sections stating that thou should first use search and\or common sense in investigating their problem, before creating a potentially useless topic.
We have it too, but I don't think it works very well

At this point I just assume most people on the internet are from America or Canada...
Bad assumption. You probably assume that because places like North America, Australia, Europe, Japan/Korea, have the highest percentage of their populations on the internet.
Or simply because the English half of the internet and the Chinese half of the internet don't have a lot of cross links, so you simply don't come across a lot of non-English pages.
