I need to add a required checkbox to the standard login form. (Users must agree to Terms of Service upon login.) I have not found any plugin to do this. Can anyone recommend a plugin?
Otherwise, can anyone suggest the best way to go about this? Can it be done without directly hacking core wp-login.php?
If I must tinker with wp-login.php, what is the cleanest way to integrate a custom field that must be validated (checkbox must be checked).
Any insight into WordPress login customization would be greatly appreciated. Thanks.
