Dear Birch,
Thanks for your question. Sorry it took so long to answer! We're going to set up alerts so that we can know when questions are posted here.
EHEALTH People is the beginning of your social network. In a few weeks, you'll be able to create user groups, like MySpace, so that you can be alerted of actions your friends take. When they post, where they post, what they post. Or send messages to everyone in your network at the same time. You'll also be able to create an "ignore list" so that people in this group are not viewed when you're online. It's helpful for eliminating conflict.
Other features will come in time...so for now, feel free to add friends. Admin is not automatically added as a friend to everyone's account (as far as I know), so is different than Tom.
