Thanks for a great plugin.
I'm finalizing a deployment and noticed that the USER-FIRST-NAME shortcode returns the person's full name instead of just the first name.
While typing this, I flipped back to the "Add New Newsletter" screen to read, and noticed it seems to differentiate between subscribers and registered users. Does this mean that if the person is simply a newsletter subscriber that the full name is returned, and if the person is a registered user in WordPress itself the first name is returned?
Also, are there any plans to separate first and last names into separate fields?
