Do yourself a favor and use another product for surveys!
I have never been so disappointed in a product. You have to use their antiquated email invitation system to send out the survey if you want to see anything beyond anonymous results. The email invitation you have to use is not user friendly and there are formatting issues. The survey itself was easy enough but trying to get it to people is the big issue.
The survey states you have the ability to forward it but when you do the link doesn't work.
