Scheduling emails and "send"

This is my first time trying to set up an email for scheduled delivery at a later date. Can someone confirm for me that the process goes like this:

• Step 1 allows you to set a "Tentative Schedule Date," but that is not the same as actually scheduling the drop, correct?
• The point at which you actually schedule the drop comes after you've marked the email as "approved." You can then "Set up delivery," and scheduling the actual date for a later drop is done then, correct?
• In order to enable that later delivery, though, you still have to hit a button that is rather nerve-wrackingly labelled "Send" (as opposed to the system being smart enough to detect that you've scheduled a later delivery and changing the button's label to something less threatening, such as "Authorize scheduled delivery"). Also correct?

I ask because I've run into a few "gotchas" in this system and I'm exceedingly leary of hitting a button that says "Send" if that's NOT what I want it to do immediately. If someone can reassure me I'm doing it right - or correct me before I do something that ruins my whole day, I'd appreciate it.
