Heads-Up: Macro Theory and Practice
Kirk from Priestly Endeavors has an in-depth series on macros running, the latest post going into the meat of things. There’s plenty of good stuff in there, regardless of whether you’re a priest or not, including basic explanation of how to write working macros and gotchas.
Of course, if you are a pallie you have a lot of your work cut out simply browsing the Altitis archives 
but Kirk goes really to the heart of the matter, true to the old saying, he teaches you to fish so you can feed yourself for the rest of your life. A definite must read.
