Our Emma account has a lightbox form with reCAPTCHA enabled, however Emma won't let this be our only sign up form. When we try to send out emails to our group it says we must select a sign up form and it won't acknowledge the lightbox one as existing. We are then forced to create another signup without reCAPTCHA and we are getting spam bot signups, at least 20 of them every single week. Is there a fix for this? Is it possible to use the lightbox form as the default form when sending out group emails?
