I've added an experimental button on the services page for email all scheduled. It's an envelope with little people next to it-- give it a try, and feedback how that works, please.
NEW: I've added a checkbox in the sendmessage window which allows messages to go out immediately. They are not queued, they don't have personalization, but all the names are included in the TO box.
