hello everybody, i am new to this website but i really like and appreciate your efforts. I would really like to help you translate the web site into Turkish. What do you think about it?

Doesn't sound bad to me. But I guess it would have to include someone to translate game reviews into turkish too. At least the newly upploaded ones.

big lebowski, send a PM to Kosta and tell him that you want to translate.

You won't need to translate the site itself, actually; somebody already did that: link.
You do still need to translate the reviews, though, which is probably the toughest bit.
