There is actually a trick that you can use to retake a survey:
If you look at the URL of the feedback page for the survey you want to re-take, it contains "_process" in its URL. If you delete that section of the URL, you should be brought back to the original survey page.
Here's the news article on this: http://www.yourmorals.org/blog/2011/11/how-to-use-groups-at-yourmorals-org/
And here's the group that the LW community just created: http://www.yourmorals.org/setgraphgroup.php?grp=623d5410f705f6a1f92c83565a3cfffc
I think it will be very interesting to see what we can all get on this.
