All of the XML, XSLT, XHTML, CSS, and PHP code on this website was created using the superb Macintosh program BBEdit.

<oXygen/> is an XML-editing suite. I use it primarily for debugging some of the more fiendishly-complex XSLT templates used on this site, but it's also capable of manually converting pages, creating schemas, and far more besides.

xScope was used extensively during layout design.

Integrity was used for testing all the links on this website.

For those of you who may be searching for a web-hosting service, I can highly recommend HostGator, which I use. Even their least expensive plan has unlimited storage space and unlimited bandwidth, for less than $6 a month. Setting up your site and maintaining it is quick and easy. You can also register a domain with them, so you're spared the hassle of dealing with multiple businesses to get your site up and running.

W3 Schools is the best all-round web-development reference site available. Ideal for beginners and advanced users alike, whether you want to introduce yourself the basics of XSLT, or want to find just the right color for an element on your page. A veritable cornucopia of information, presented in an easily-understood form.

Art Text — very useful for creating banners and decorative text-based images

EasyBatchPhoto — the perfect utility for shrinking pictures, and converting them from one format to another, with plenty of scalable options for quality and size
