I've made a WoW Launcher that is much better then the others (and I know there are many) out there. It looks like the normal WoW launcher and is very user friendly. Its features include, obviously, launching WoW, changing your realmlist and deletes your cache and wtf folders, auto-detecting your WoW directory, and it has a built in web browser that goes to XtremeTop100.com - Gaming top 100 list so you can pick some new servers when you need to. There are two versions of this program, one for the 2.4 version of WoW if you play on a pre-wotlk server and a 3.0 and later version.
Note: When connecting to a private server, you must have your directory found, the auto-detection feature needs to know your OS so it knows what folders to look for your WoW directory. When you type the servers realmlist in the appropriate text box, you don't need the SET Realmlist part it will do that for you.

I know the 3.0 version had a 1/40 but I guarantee you that both programs are completely safe.
Also, thanks to Kirth for the idea of the auto-detecting directory. And thanks to everyone else for their ideas. I planned on adding more things soon like letting your change the URL in the browser and saving realms etc. but I just made this in a few hours so I didn't really focus for everything. I'll be doing more stuff soon maybe tonight even.
