Other than providing a good medium for regular publication, my favorite aspect of blogs is RSS capability - bottom line: my favorite writers' content comes to me via a single RSS reader (more on RSS readers coming soon).
But not everyone's into RSS. Some of your readers might be better served by an email update.
You'll notice a new option in the right hand column of the Church 2.0 site inviting you to subscribe to Church 2.0 updates via email. This handy piece of code allows you to get your content out by email (in addition to the normal RSS) without doing anything more than posting to your blog.
In our case, we're using Feedburner to handle this process. Set-up is easy and you'll be walked through step-by-step. There are a few customization options if you want to personalize your messages, but that's all completely optional.
