Some have said they can't see their group members.   The most common reason for this:  You are not connected to a group.  

Each year we begin with preseason and people are invitied to build groups during that time.    By default, group members are then "connected" to that preseason group.   When the real season starts, the new games are inserted and the preseason games are removed.    What results:  When you login, you will no longer be connected to your group.     (Look for the Join or Create a Group! message)    

The other way this can happen (not being attached to a group) is when a group manager removes you from their group.   Group managers have red Xs next to each person in their group.  If they don't want you in, that red X will remove you.   (It removes you from the group, but does not delete any of your data)

The most common reason this happens:  You just registered and didn't complete the process.   You must register, then join a group.  (95% of the groups here are private, so you must also know the group code)

Anyway, to fix this is pretty simple:   

Within the control panel click the Select Groups icon.     Join your grouip by entering the group code and you'll be back in.   (Remember, you can join more than one group.   To move from one to the other, you would use the same Select Groups icon)
