Wufoo is a very effective and easy to use form building tool that allows normal people (i.e. marketing managers and other non-techies) to build web forms quickly and easily without knowing programming. The form entries are collected in a database, and can be exported out to Microsoft Excel.
Or, isn’t Excel the marketing manager’s best friend?
You can have your designers make design changes with a CSS editing area, but the forms are designed to be very usable (I was impressed), and for short term form management, this is a great tool. For a longer term project, it’s better to go with custom programming.
