Well,

Welcome to the world of Multiboxing, firstly. You really should read the WIKI and some of the stickies, particularly some of the awesome tutorials from start to finish. Excellent stuff. You should also be aware that playing your's and your wife's account simultaneously is NOT a good idea. It has been discussed at length repeatedly around here. If you truly wish to venture into boxing you need to get yourself a 2nd account in either name and play only the two matching accounts together. There's nothing saying your wife can't play alongside your 2-box... but linking her's along with yours as a clone is a clear ToS nono.

Anywho, 1st thing's 1st. Check out the great info here, it will help you narrow your questions down to specifics and give you at least a basic understanding of what we do.
