I've seen a lot of customization questions, but I still haven't seen how to just change the text of the CreateUser button. It seems that the button it automatically showing despite already switching it to a custom template.
Nevermind, I'm an idiot. I had looked for a simple line to change it the other day when I was in a hurry (in front of the customer) and didn't find it. I figured it wasn't there, but it was.
CreateUserButtonText="whatever you want"
