Can you give me a link to that group?
And yes, you can reply in Polish, it's not a problem with understanding, but with my speed of typing.

Hello guys. Despite currently I live and study in Wroclaw, I feel better typing in English, because Polish isn't my native language. Sorry about that again, it is easier for me to speak than to write. 
You still have meetings on Tuesdays? Because I didnt notice any forums actiity lately.
