I think one of the interesting things is that as people are using computerized tax services—so even if they're not using a personalized tax service to do their taxes—it's not uncommon for the software to ask you, “Did you donate? Are you aware of this?” That raises a very interesting thing about creating more knowledge for people. That's something we really haven't studied, or I don't know of anybody who has studied that particular phenomenon. But there is probably an issue about what information is out there.
The other issue is that these are non-refundable tax credits.
