Annotations Vs. Notes on Personal Games

I am wondering about Annotating my current game. If I am not a Paying member, do I still get to annotate one of my current games? I noticed that I could type notes on my game, but it only allows a limited number of characters.

If I do get to annotate my current game, will my opponent get to see what I have typed? How much annotation am I allowed for the game?

I am a non-subscriber and I just went to my finished game to see if I could annotate games and I could, so you could too.
