Yeah the matching donations was the obvious answer. It's honestly a decent way to do charity as a company (obviously bigger ticket contributions are good, too), because it rewards them for their choices by increasing their value, and your contributions are going places that have some support behind them from your employees. Finding worthwhile causes that don't get money has value, but it's really hard and expensive to do.
Unrelated to this post at all, I'm a bit out of the loop on this, is there something wrong with PDFs? Just wondering what the PDF warning is about, this just being the first I've ever seen that.
