Never heard of amazon smile before, but there registry of charities to donate to is really hard to ensure you got the right one.
I set mine to "Signal Technology Foundation" which I am fairly sure is correct, but there is no link, no description or other method to verify; it doesn't spark a lot of confidence.
And if that wasn't confusing enough, Signal et al call the foundation "The Signal Foundation" while the proper, official name is "Signal Technology Foundation".
