It would be really cool to see Community Builder have a feature commonly known as "Follow Me" which makes it so that users can Subscribe to individual members. This would make it so that every time the member who you are "following" (subscribed) to posts an article, you would receive a email.
Kinda like youtube. This makes it so that you can more easily keep track of your friend's post as well as people who write interesting articles.
Awesome! Glad to hear that it is already possible, but in my case would rather a individual bases for "following" rather than notified about group activity. Sounds like CB 2.0 will be fabulous.
