To be honest, we've never met someone involved in a wedding who isn't a little stressed about etiquette. There are classes and books available, but they're not for everyone. We recently came across the Mr. Manners' Quick and Dirty Tips for a More Polite Life podcast. This is a free podcast offering very general etiquette tips in short audio files. You can listen online, or subscribe and listen via your iPod or whatever. This podcast is also available via iTunes at http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=203228276. You can now brush up on your etiquette on your own schedule!
