It's a bit of a mongrel, in terms of design tools... Originally it was done in Microsoft Publisher, when I had zero html understanding... I've been using Dreamweaver since last summer, and it's now used for 99% of the new stuff, with Photoshop providing the graphics.
The domain is mine... groan... after getting kicked off of my ISP webspace for bandwidth abuse. Ick. But that's sorted, the site's back and will be developing apace over the summer, with lots of new features and two sister sites, which I'm just beginning work on.
