Teachers often use Blogger as a way to communicate with their students and parents; one feature that comes in handy is an RSS feed. This allows students and parents to sign up to receive new posts directly in their email account. The first step is to log in to Blogger and go to the Layout section. You can then Add a Gadget to your blog. When the list of possible gadgets shows up, choose Follow by Email from the list. Now you have a button on your blog that will allow anyone to subscribe to your blog. The screen shots of this process are available on this post. Happy blogging!
