I have posted some of the better ones that I have found scattered throughout posts on this forum to an article on WOWWIKI. I am trying to get the good ones and some explanation as to why they are good choices.

If there are errors on the wowwiki article let me know and I will correct them. You can also follow the links in the article to other pages related to multiboxing in WOW. I took Xzin's original FAQ and split it across 3 pages and added more related pages - like this one on good multiboxing macros.
