Perfect solution to a problem that shouldn’t exist

This was exactly what is was looking for.
I think more people are going to be installing this plugin shortly.

And if the WordPress dev team happens to read this.
Why would you come up with this autocomplete nonsense?
I don’t get it. Why would I be constantly be adding an email address to text blocks that belong to a site user?
Emails are not that long. There is no reason for the autocomplete feature.

Anyway, thank you to Jb for making this.
