So did you actually go to a meeting yet, Russell, or pick up an Alanon book like "How Alanon Works" (probably a great starting place) or "Paths to Recovery"? The books are available used on Amazon at a very reasonable price. It's about the easiest way to look into Alanon that I can imagine.
There are also a ton of other threads here where people asked about Alanon . A quick search of the site will give you even more info.
