Trial expiry for 3.0

How can we know when the trial period for v 3.0 is about to or has expired? Stops working, email notification, etc.?

You will receive email notifications as you approach the end of trial.

Since the Xbench 3.0 trial is for days of use instead of calendar days so that you can properly evaluate it, it may last a lot if you only use it from time to time.
