(Don't take it abusive.)

1. Don't SHOUT!
2. Use words, not numbers. To is to, not 2!
3. Don't use chat English. Because is because, not coz!

I don't know if such books exist, but I'm sure they exist.
Well, you can tell us what is in your mind ;-)
I'm sure we can tell you if it's good or not.

Cheers!
