This is a neat little "bug" that I found yesterday. It makes it possible to use a wand that you've got on your alt on your main and get credit for it.
Requirements:
A main.
An alt with a wand.
A friend on your server.
First, start off with placing your main and your alt close to eachother. Make your friend invite your main. Open up another instance of wow, disconnect yourself, and log onto your alt. Make your friend invite your alt to the same group. Your main will still be in the game for about a minute, and during this time you can use the wand on him. Relog your main and PROFIT!
I hope some of you will find this useful. It will save you a few gold if you don't want to buy wands from others.
