Talkdep is been a great help to me when starting with CD.
Great topics...and prob the most used and most handy ones are the betting topics. I have made tons of money already because of them, and wanna thank everybody that contributes in those topics.
Also, our Teamforum is good to follow, we dicuss tactics and other stuff... communication in games like these are important

so Talkdep is certainly worth of checking out
