Ok, so i don't want to 5 box or anything, but I would like to be able to use my 70 Shaman to run my 39 warrior through some instances.

I will be using one monitor, but how do I run 2 instances of wow?

I saw something along the lines or copying the entire WoW directory to another subdirectory (not in the wow folder) and then renaming the .exe to wow1.exe instead of wow.exe. Is that it? Then simply have 2 short cuts on my desktop to run two instances? Is it that simple?

Then I can just alt-tab to switch between the two? Or do I need to mess with other settings/options/etc?

I know this looks like everyone else's questions regarding 2 boxing, but I am not wanting to control 2 same characters to mimic each other, I want to put one on follow and control the higher char, I have read some of the posts before doing this, but am a little confused still.
