Getting on Xbox Live is simple if you have a high speed internet connection. Make sure your 360 is connected to the internet either directly to the modem or by using the Xbox wireless adapter. When you turn on the 360 for the first time, you should be prompted to create a gamertag and gold membership. Use the 48 hour free trial to make your avatar, play some games with friends online, download a hot game demo, and see if you like the service. When the trial is up, membership fees range from $7.99 per month to $15-20 every three months to $35-50 per year depending on where you purchase your membership.
