If you want your own domain name you can register it with your favorite Domain Registrar for $10-30/year
How to Start:
Recommended but not required: Set up a Gmail Account at https://mail.google.com/ for the AYSO region, area, section, or desired entity. This master account should be the primary owner of all Google based assets (sites, docs, calendars, photos, etc).
Go to https://sites.google.com and login with the master account.
Push the "Create" button and follow the instructions to create your site. Enter information as desired.
Click the blue "Share" button in the upper corner to grant read access to everyone and edit access to those you want to help you update the site. Individuals should use their own personal Google Accounts when uploading and editing so changes can be tracked. Any email address can be a Google Account.
