I have seen the Greek team writing all posts in both Greek and English in blocks
A
A translated
B
B translated
C
C translated

conclusion

I understand a little Spanish French Greek German if it gets to hard I use Googletranslate
if I would write a post in Dutch I would use the block method to open the post to other language zones
If I write in English i keep it just in English

Nice. Thnaks for answer, I will keep it in mind :)
