So I just discovered there is (was) also a
UL Finnic Cafe with posts in Finnish, Estonian, Moksha, and Votic on the General Languages forum. But it got buried. And way back there was also one called
Same Topic About Finno-Ugric Languages, which suffered the same fate.
There's also a
Khanty and Mansi thread on the Hungarian forum and
something about Udmurt on the Russian forum which I think is the
same as this one in English.
I don't think the
Uralic Languages Word-Association Game has been mentioned yet either. It's not a specific language, but it certainly could go on the Uralic Languages forum if one is created. Currently it has posts for Estonian, Finnish, Hungarian, Udmurt, Northern Saami, Komi, Meadow Mari, Livonian, Võro, probably others since I didn't look through all the pages.
I'm not sure what else there is. It's hard to even search for the threads because they are so scattered (General Language forum, Other Languages forum, Saami forum, Russian forum, etc.) Most are not currently active, but that's probably related to them being so hard to find. The search function is only useful to a point because so many of these languages have multiple names (Ingrian/Izhorian, Votic/Votian/Vod, Olonets/Livvi/Karelian, etc.) Being scattered across several boards as they are, they are very hard to find. I've been here for two years but hadn't found most of these threads until now, and that's after a lot of searching. At least this thread helps us get all the links in one place. That's a start.
