any one use notes to help them?

I have bad memory, so I use chess.com's notes to remember what I was thinking.

In e-mail chess? Of course! If you don't, you are cheating yourself out of a valuable resource. Everyone should definitely write down the calculation they do and main variations that they figure out somewhere. Otherwise, you would just be starting over from scratch each time. Unless you just have an incredible memory, or if you don't analyze that deep. An analysis board and the notes that come from it are my main weapon. Way more potent than any books or databases or anything else you can conjure up.

Is this how you approach e-mail chess? 

i dont use them, ive actually just noticed them!!

I don't use notes or the analysis board.  I play the games as though they are over a real chessboard.   I guess that would put me at a disadvantage but I think It will help improve in the long run.   It's for fun anyway.

That's why I don't use an analysis board. But I use notes, because I figure in a real game I am not going to forget what I was thinking between moves.
