I'm very interested in a U.S. version of this plugin to incorporate Mission Fish or any other multi-charity service. I have always been a big fan of rounding up when I make purchases with GoDaddy and I'm sure my customers in the U.S. will love this option as well!
Do you have anything in the works for a U.S. version? Thanks!
MisshionFish seems like a good fit for our plugin. Do you have or know any websites that are currently using it in their checkout so that we can have a look? Also are you aware of any public documentation or API on how to integrate with their system?
Thank you for offering to take this on! I just found out MissionFish is now owned by PayPal and they aren't sharing the service outside of PayPal and Ebay, but there appears to another good one called "The Giving Lab" with an API and full developer suite: http://www.thegivinglab.org/platform/
Hope that helps!
