Use Goodsearch when you're searching online and they make a little donation to the charity of your choice for each search. I've been using it for a while but decided to post about it because Kansas Dad's university is now accepting donations. Let me know if you want to select them but don't know the name of the university.
Just so you know, Kansas Dad does not recommend using it to search for potentially plagiarized phrases. It's just not as robust as Google for stuff like that. I think most of you aren't doing those kinds of searches on a regular basis, though.
