Allow subscribing to teams/events

I do not check the LoCo Directory often. However, as a member of the Chicago LoCo, I would be interested in knowing when other people create a new event for the team. I am sure other people in the LoCo would feel the same way. Currently, the only way to know this is to either check the LD or for someone to make an announcement. The ability to subscribe to a team and get email notifications would be very useful. Similarly, once an event has been created, it would also be useful for people to be able to subscribe to the event to get updates about attendance, changes to the event, and comments.
