Has anyone found a way that a guest can submit a guest review on Homeaway without having to sign up or login in order to submit their review?  It is hard enough to ask guests to submit reviews but once it looks like they have to sign up for something they just stop the process.  We shouldn't be making it harder for our guests to participate in the review process but it is nearly impossible to get a review posted from either Homeaway or VacationRentals.com.
