Learning chess

I only got into chess about 2 years ago and it all started to make sense just in the last 4 months. After going through all the training and execise, I only know a fraction of chess. There is alot of studing and learning, it just goes on and on. I am not ready to play the big players yet but someday I hope to be up there.

What are other goods programs that are helpful and improve your skills in chess?
