A couple of ways, in my view, would be to do these two things: a) any OTB games you play, write the moves in algebraic - you will quickly get used to the notation that way, and b) while playing here, add the numbers and letters to the board by going into your Control Panel and changing the Settings for Online and Live to include these.
Best wishes on learning the algebraic system; it is far more precise and concise than the older notation, again, in my view.
For a beginner what is the most efficient way to familariaze yourself with it? I find it hard to cope with chess books etc
