I realize that some of the criteria are quite demanding. I have tried to structure the list so that all of the potentially subjective criteria are not on the Critical list. Users should keep in mind that any site that receives a grade is most likely a legitimate site. What separates an A from a C is largely accessibility, design, and other elements that make the site easy and pleasurable to use. I anticipate that very few sites will get As, but I hope they are prompted to improve.
Some sites have multiple charities, and in some cases a parent site manages several one-click sites.
For example, Ecology Fund has many charities, but manages them all on a single site. This distinction allows me to give thorough reviews where items could differ from site to site under a single parent, but spares me from performing duplicate reviews for sites that do not warrant individual treatment. This is a very rare grade, indicating the best of the best. If a site fails to meet all Critical criteria, it will get this rating, even if all Important and Useful criteria are met. I also reserve the right to make subjective decisions on grading, including but not limited to adjusting grades based on overall performance.
