RENXT gives us the ability to create donation forms and generates HTML code to embed these donation forms on the website. We need the ability to create a newsletter signup form with custom fields, so people can sign up for our various newsletters from the website. Online Express only allows us to create a form with First Name, Last Name, and email address. We need the flexibility to create custom fields to respect our constituents' communication preferences, so they can sign up for general updates, fundraising emails, program updates etc.
