[Groups help] follow

Syntax: follow 

Follow will ensure that you walk with the person whom you have chosen to
follow.  You will be unable to follow someone who is already following you.
Furthermore, if the person you choose to follow is following someone else
that is in the room with you, you will follow their leaders instead.  If
that leader is not in the room, you will be unable to follow them.  In the
case of complicated chains of followers, you will not be able to follow
someone who is ultimately following you.
