All good things must come to an end. Google Apps, the free edition of Google’s awesome web and email service, has begun emailing users to let them know that from now on Google Apps will allow 10 users for each account before upgrading to the paid Google Apps Business Edition. Previously, Google Apps was free for up to 50 users.

As a courtesy, existing users are being grandfathered and will be able to continue using Google Apps for free with up to 50 users.
