The web site Capterra, which lists all sorts of software by categories, has listings for DONATION in several categories, such as Donor Management. They have recently instituted a user rating system, where you can submit your brief review.
If you have a few minutes, and feel so inclined, perhaps you could review DONATION there, at:

Thank you!
