I think a neutral or negative review is good for everyone - including the vendor. They have a chance to make up for a poor shipment, review and change their practices, or explain their side of the story. All good information. Only allowing positive recommendations makes no sense to me. As Lauribob pointed out, sometimes a person may have a great experience (positive review) and another time a not so great experience (neutral or negative review). Ordering live plants is chancy to begin with, and more information is certainly better than less.
I think that feature is still available without being a registered member on Dave's Garden, although I haven't checked in there for quite some time so things may have changed.
