If you would like to use custom icons for your macros, you can place them in your World of Warcraft\Interface\Icons folder (creating this folder if it doesn't exist). The files must follow the same guidelines for UI textures. Namely, they must be either BLP files or 24-bit/24-bit+alpha uncompressed TGA files. Their dimensions must be powers of two up to 512 (e.g. 32x32, 512x128). Note: any images that aren't square will look squished on your action bar.

Keeping macros on multiple computers

Until Blizzard decides to store macros on the server, you must copy your World of Warcraft\WTF\Account\Youraccountname folder between computers. This will also preserve all of your settings for any addons you have installed, though the addons will also have to be installed on each computer.

If you would rather have your macros and nothing else, you need to copy World of Warcraft\WTF\Account\Youraccountname\macros-cache.txt for your general macros, and World of Warcraft\WTF\Account\Youraccountname\Yourrealmname\Yourcharactername\macros-cache.txt for character-specific macros.

More Information

If you have a specific question and did not find your answer here, check out the Macro FAQ & Repository (http://forums.worldofwarcraft.com/thread.html?topicId=108386180). It contains answers to quite a few questions as well as numerous example macros. You should also take a look at http://www.wowwiki.com for more inspiration. There are a number of macro-related articles as well as details of the WoW API for use with scripts (/run).

Finally, don't be shy to ask questions on the forums. As long as you understand the basics that this guide has presented and you demonstrate an effort to solve the problem yourself, the posters will be more than happy to help.

Thanks also have to go out to Iriel, Tem, Cladhaire, and others who are intimately familiar with the WoW UI and have shared their knowledge with the rest of the world.

Some other characters roaming around that deserve some recognition for their contributions to the community are Neuro, Shirik, Jelly, Lunessa, Troodi, Lealla, Aella, Valaron, Lopeppeppy, Kamdis and plenty of others I'm forgetting as I am wont to do.

Finally, I'd like to recognize the contributors on WoWWiki who have worked to spruce up this article in wiki form, correct my spelling, and add new tidbits of information while I've been slacking off writing a book.
