Really great module -- does the trick, right out the box!
Under modal_form settings config, Login has the "Display links" options, but Register and Forgot password forms do not. Is it not needed? Am I missing something? I am thinking about the typical expectation that as a web site visitor, I can click around a few times to determine whether I have an account, whether I want to reset, etc all from the original "login or register" type link.
