I'm at the first step of planning a transition from our existing student email system, Netmail to Google Mail (for educators version). I have three schools to handle, three separate domains and about 2K kids per domain.
Here are my main concerns
Integration with our new website (coming very soon).
Also, we have to determine our responsibilities for archiving and retrieval of student messages.
ps- am now testing with a fake domain- can I disable chat and address book search in Gmail?
