Please note: A new version of this website is now under construction. The current site you are viewing is an older site that runs on older technology and so it cannot be easily upgraded. So while I do plan to keep this site active just as an archive (since it has achieved high search rankings for many topics), I do not plan to add any more content to this particular site. Please stay tuned for more information. I will post the domain name of the new site here once it is ready to go online. Thank you.
