Hopefully people will want to buy and install PCDB SuDoku Solver, and if they do we need to know what to do with their money. The answer is that I now have a Google Merchant Account so that Google can pay me, on a regular basis, any proceeds from people downloading the app.
It helps if people know we're here. So the site's front page now includes a Facebook "Like" button. Gosh, the amount of new technology I've had to master to get this app up and running!
