I created a Google Docs Form for this. It can be accessed via: http://spreadsheets.google.com/embeddedform?key=rIpaN9uOwhiJnq2I0jqMPPw
Google automatically summarizes this data for us, also it can be made public. For results goto: http://spreadsheets.google.com/pub?key=rIpaN9uOwhiJnq2I0jqMPPw&output=html
