The main addition is a "user account" system which keeps track of

gamertags(this can be made public or private) and allows access to

certain pages on the site.  The registration is free and takes less

than a minute.  When registering the user can add their gamertag and

an optional alternate gamertag into the database.  This list can be

sorted by state and searched through.  They have also added a system to

help people organize get-togethers over xbox live.  The user can post

a the start and finish time of the event along with a name and

description.  You can sort through the database by either events

happening this month or events happening on the current day.
