Very nice. Thumps up.

Two things you might consider mentioning.

1. The fact that you can't send or receive tells while you're in an instance. I'm pretty sure the game tells you this if you try it, but new players might not catch that.

2. /blist add <r>. Or, in general, the fact that <r> expands to the name of the last person to send you a tell. It's just that this is the most common use for it, and it makes for a handy macro on servers that are really plagued with RMT spam.
