I find there are topics posted in Russian or other languages too.
This forum is very informative therefore in order to learn more about JM also not to duplicate topics, iis there any default option to read other language topics in English (or vice verso).
Anyone can use Google to translate the posts, not that it makes it easier to understand...
I would suggest splitting the forum to two sections, and English only and a Russian only. Of course I would prefer if everything was in English (or even better, Hungarian ) to avoid duplicates but obviously there's a need for Russian section. A simple bi-lingual forum would be easier to follow.
