ConcourseConnect's latest feature: Email Updates. 

Email updates allow users to opt-in to receive emails about activity that is going on in the community.  For example, let's say you become a member of a project.  If you are an active participant, you might want to be notified several times a day about activity that is occurring in the project.  The email update is a list of who did what, including posts in the forums, blog posts, new files, announcements and more.  When joining a profile, the user sees the notification options...

Users can decide per profile (whether a project, group, department and more) as to whether that profile's activities are sent daily, weekly or monthly.  The notification preferences are also summarized on the user's own profile page for at-a-glance modifications and navigation.

There have also been many tweaks to the user interface.  Please explore and comment as to whether you like them or not!
