A host Web page includes an evolving interactive dialog box wherein an Internet user may enter user data to be processed. When the user completes entering user data in a first revolution of the interactive dialog box, the first revolution is replaced with a second revolution of the evolving interactive dialog box without disturbing or affecting any other part of the host Web page being displayed. Beneficially, the first and second revolutions may be communicated to a user computer together with and at a same time as the host Web page. Also, the second revolution may include a variety of data which is selected or customized to match the user data submitted in the first revolution. Each revolution of the evolving interactive dialog box may be comprised of any combination of general textual data entry fields, category (pull-down) menus, contact information data entry fields, and opt-in/opt-out buttons. The evolving interactive dialog box may also include dynamically selectable features, such as font type, font size, font color, box shape, box dimension(s), background colors, foreground colors, etc.
