Let me start off by saying, I dont take credit for this. It was taken from wowscape. There program. I'm showing you how to get it and how to set it up.
Lets start off.
Download-
http://wowscape.net/wsl/wsl-3.3.zip
How to setup
-------------
1. Once the file is done downloading, extract it too your desktop.
2. Begin the Setup process
3. Once complete, run the new "WSL".
4. To complete the process, go too settings, then click browse and find your WoW folder and hit select (the folder with all the world of warcraft data in it.)
5. Once thats complete you will notice on the server thing there are a list of servers. Simply click one and hit launch wow and it will automatically change your realm and start wow. Notice though, you can add other servers by click "add server". Put in the name and the adress and w00t!
There is also a global chat that people will be more than willing too help on.
