Bravo. It's weird sort of moral pretzel to advertise your donations which simultaneously wins you some respect and a whole lot of antipathy for being self-righteous. Unfortunately there's no way I know of to self-advertise your donations without being self-righteous but it's the right thing to do. Ironically you find yourself wondering do you pay more with your pocketbook for the charity or more with your social capital for the charity advertisement (which makes the charity more impactful).

By the way I don't donate anything to charity at the moment, although I plan to someday. So I'm speaking from a no-skin-in-the-game perspective.
