Thanks for the great plugin.
I was using Google Forms to use as my contact form. (I run a holiday accommodation site and had a Google Form widget next to each holiday accommodation page so that people can enquire about the home from the current page they are at).
But I had endless trouble with Google From spam. If you are interested in reading about my issues and possible solution go here http://goo.gl/TgZhb
This contact form 7 db plugin gives me all options I want but one; it does not write the form data to my Google Spreadsheet. I know I can download the new data from CF7 DB to a Google Spreadsheet but I want to push it a little further and ask that the Google Spreadsheet becomes the database. This writing new contact form entries to a Google Spreadsheet.
I am willing to pay for such functionality ;-)
