Provide an alternate to forms
Forms should not be the only way for users to communicate and interact with the individuals, companies, and organizations represented on the Web. A Web site with only forms—no email address, street address, or phone number—is unwelcoming to users who cannot use forms or who prefer to communicate some other way. Forms come with enough technical complexity that some users will inevitably have problems submitting information or ordering items using forms. A phone conversation may be a more effective means of communication than submitting a query over the Web. Web sites that rely solely on forms risk losing users who cannot or choose not to use forms.
Always include alternate methods for making contact, such as a street address, phone number, and email address.
