Google has ended its free sign-ups for Google Apps today. Before, anyone with a domain name could set up a free Google Apps for their domain name as long as they would have 10 or less users.
If you signed up your organization for a free Google Apps account in the past, it will stay free – unless you decide to upgrade.
501(c)(3) non-profit groups with less than 3000 users can still sign up for Google Apps for free through Google’s site for non-profits.
