Can you send me updates by email?

I was just in the community trying to find out why Sandy's email looks different. I made me wonder if there's somewhere I can sign up to get information about updates sent to me by email. I like knowing about the new features but I don't often go to the community section. When I do go to the community, I don't have time to look through a lot of messages so I usually just read what's new and what's popular. I know this means I miss important stuff if I doesn't happen to be in one of those categories. So, my question is, it is possible to get important updates or information about major changes sent to me some other way, like email? Or even a note on my Daily Digest saying "check out new features in the community" or something like that. Thanks.
