Is there a way I can get notification centre alerts for email without having the mail.app run in the background? (i.e. like push on my iOS devices, using gmail through exchange) Also I don't use iMessage at all but may in the future and am wondering if the same applies there, i.e. does the Messages.app need to be running for notification center to display iMessages or is that pushed from iCloud regardless of whether the app is running or not? Liking ML so far... Cheers!
