When do we get to translate Swedish articles
Translation option isn't showing up for me yet, is that because I haven't progress far enough into my tree?
Also, will there be the reverse translation option?
Swedish Immersion hasn't been added yet, so it has nothing to do with you - it's just not implemented. Hopefully it'll be here soon, now that the course is out of beta. :)
I don't know whether a reverse translation option will be added, but at the moment no other courses have it (except through the reverse tree when it's present), so I wouldn't count on it.
