About post-USSR, my native language is russian and Russia turns more others languages in daily use, i think need select importent goal for support it.

I don't completely understand what you said here, i assume your english is not very good (English is also not my first language so i understand getting good at it is tough, just keep reading and practicing!, I think it's one of the most useful skills you can ever work on).

If the main problem is that you don't know english well and can't provide a translation have a look at how liberapay does it (look at the upper right corner of the homepage). you could have others provide a english translation (but probably the sooner you will add a translation infrastructure the better).

Cool project btw!
