Most CHCS email customers are using email from Google Apps. Google is making changes that will allow you to access to a myriad of other Google services. This was announced a year ago, and the transition is being completed shortly.
If you are a Google Apps administrator, you have been receiving notifications that all Google Apps accounts will become "enhanced" with the additional services in the next couple of weeks.
Please contact CHCS if you have questions. Detailed help about the transition is available from Google.
In another change, effective May 10, companies that sign up for the no-cost version of Google Apps will be limited to 10 users. Organizations with existing free Google Apps accounts will continue to be able to create up to 50 accounts. Schools and other nonprofits using the Education version will not be affected.
