I usually need to update my posts when there have new information. As default feedburner don't send email notification when the post is update but I check another site (using custom template), he create an update page and each time he post on it, reader will get feedburner email notiication, but it's not new post. It's old post (the post that just has been updating) and the information that just has been updated.

Can I create something like that in wordpress?
