online "tells"

[tourneyplayer]

I am a relatively new player (at least I'm new at being good and thinking hard about the game). I've put money online and had success. Awhile ago I switched to tourneys only...which is why I posted here.

In face to face games, I do very well picking up tells. Caro's book helped me quite a bit. Are there any online equivalents to such? Any at all?
Perhaps betting time, typed messages, ...I don't know.

I've tried taking notes and that helps me some.

One more thing...I saw a post about a tournament book called "Aleo's" ...what is that? where can I pick it up?
