As a volunteer webmaster for a number of local non-profit organizations, I've searched endlessly for a WP donations plugin that could be easily implemented, had standard PayPal integration, and (MOST IMPORTANTLY) allowed for honorary or memorial donations. The majority of plugins I ran across were either too simple (only donation amounts could be entered with no option for extra information like honorary donations, etc.), or too complicated (practically setting up a full e-commerce store for what should be a simple transaction). Seamless Donations is an absolute godsend. It took less than 10 minutes to install it and run a few test donations through my PayPal sandbox account. So far everything works PERFECTLY. In case the developers are reading this, though, the ONLY drawback (and the reason I'm rating this 4 out of 5 stars) is that the donation form is not customizable. It would be nice to be able to add an extra field or two, such as an Optional Comments field or something of the sort (many donors send honorary / memorial donations in honor of a holiday or someone's birthday). Otherwise, fantastic plugin!
