Please note: Asking people for more than their name and email address upon first signing up can drastically drop your opt-in rates. When you are using a lightbox form for initial signup purposes, it's best to only ask your subscribers for the information you're going to use (like name and email), then once your subscribers are invested in your content, ask for more details about them.
