SurveyFly: Deleting a retired quiz….

I’m using Surveyfly on one of our websites, to um, do surveys!

It’s fairly straight forward to retire a survey, but I was just wondering if anyone knows of an easy way to delete a survey all together?

I’m happy to start hacking away the database with sql and phpmyadmin, but, only if I know what I’m supposed to be deleting.

I’ve had a little look, but haven’t got the confidence to do it yet, because the site it’s running on is considered quite important.
