Is there a Course Request discussion for the Swedish forum?
The Guide to Requesting a Course sad to put it in the forum for that language. I can't seem to find one for Swedish.
It would be very nice to have a Finnish/Swedish speakers course.
There's no forum for Swedish because there are no courses for Swedish speakers. Duo has told us it is reluctant to add more 'from' languages because then they'd have to translate the whole interface of the site into yet another language.
So you'd have to use the general, English forums for that.
On the right of the discussions screen is a list of the forums you are subscribed to. If Swedish is not in the list then select edit and select ,swedish from the pop up list.
