Is it possible to set up an online survey and frontpage collate the responses?

An online survey can be setup using any HTML application.
The basics would be creating a page that has all your questions, and a space to type or choose the answers.
Use the INSERT > FORM menu to do this.

The technical part would be enabling the form to submit the information to your desired location. You can send the information to the following:

Simple options:
Email address
File - HTML or Text

Advanced options (requires programming):
Script
Database

You will need to play around with the settings and test the system extensively before making it live, as small errors cause the process to fail.
