Jim,
Does the green banner you refer to mention the short time scale?
No, it does not. What I quoted is all it says.
If not perhaps I should raise that on beta? It seems essential for
some people.
I think that's a very good idea.
In fact, the page is rather blank. Maybe it should cite the Subject line, and To & From addresses of the sent message to help the member identify it. And suggest that the member check their Spam folder if it is not in their Inbox. It could even suggest white-listing the From address.
See what you think. Go to the site, log out if you're logged in. Click Log In near the upper right, and click the button. It won't harm anything. That will also give you an opportunity to review the email that is sent.
