The downloads page has both the "single-user" version of Gmail Notifier and the new "multi-user" (for Google Apps) version. I currently have the "single-user" version, as I only have one Google Apps account I want to check on. I'm confused though -- is the new "multi-user" version an update to the existing "single-user" version (in which case I probably want to download it at some point just to get whatever bug fixes, etc.) there might be)? Or is it a separate product (in which case I don't need it)? Could you shed some light on this? Thanks.

Actually New multi-user notifier is a seperate product itself. It supports checking email notifications for 10 email accounts simultaneously.

The one majore difference is that multi-user notifier automatically login-in to Google Apps when you "view-inbox"  or "compose" new email message. It also includes small bug fixes which were present in the old version.

Thanks
