Apart from the signup screen, the TOS clause would also have to be on the accept invitation screen. It would be great to have a customizable text element that is shown on both of these pages because the CSS workaround is too limited because content does not take any html.
Or perhaps it would make more sense instead to display the custom user fields also on the accept invitation screen? It is currently possible to construct your TOS accept clause as a custom usrr field that is required at signup but unfortunately there seems to be no way to display these for invited users.
Any chance that this will be changed?
