Hi radost thanks a lot for your translations. Our bulgarian experts don't come here very often so I will validate them myself. I didn't have time to do it until now.
Don't forget to keep the tags [..] [/..] %s %u ect.. in your translations are they are often used to be dynamically replaced by a text.
You made some comments on some translations, could you translate your messages in english as we can all understand them?
