Why did you decide to start the FK4 website instead of posting the episodes on a fan fiction list or putting them on one of the archive sites?
When I got a new computer in 2004, I searched for Forever Knight on the Internet.  I quickly discovered the FORKNI-L and FKFIC-L lists, and the major archives of Forever Knight fan fiction.  But I also learned that posting stories required converting them into text format.
I had written everything on my old computer, whose wordprocessing software was WordPerfect 5.1 for DOS (which, indeed, I still use).  Although it would be possible to preserve some of the formatting if I converted to text, it would not be possible to keep everything.  In particular, the page breaks would have to go.  This would seriously affect the appearance of the episodes I had written.  It would also take me a long time to alter the episodes page by page so that now-unwanted material would not intrude inexplicably, thus confusing the reader.
So, I thought I’d try to figure out a way to offer Season IV to other fans without altering it in any way.  The most efficient method turned out to be to put the episodes in zip files without changing the format at all, and link access to these zip files through a personal website.

Where did you learn about website and webpage design?
From books.  The first one I bought was Creating Web Pages for DUMMIES (by Bud Smith & Arthur Bebak), from which I learned enough about WYSIWYG programs to realize that that was not the way I wanted to go.  I wanted something more flexible.  Well, okay—basically, I wanted something that was totally mine:  my vision.  This decided me to learn HTML so that I could write my own pages.
The other books were bought simultaneously, simply because I couldn’t decide between them.  I first read HTML 4 for DUMMIES (by Ed Tittel & Natanya Pitts), and then Creating Cool Web Sites with HTML, XHTML, and CSS (by Dave Taylor)—which, by the way, turned out to be the best order to read them in.  I picked the first one because I’d found the “DUMMIES” series to be eminently readable; and the second because, while all of them talked about italics and boldface, it was the only one to mention a way to use small-caps (something that I’ve been using for years in word-processing).
Once I’d read all three books, I then went to a website mentioned in one of them, and played for a bit with the hexcodes used to describe colour, working out sets of colours that work well together.
Then I wrote my first webpage.  For those who are curious, it was a version of the ratings page.  I did three colour variants (for PG, 14+, and 18+).  Although I have since revised the page, tightening up the HTML a bit, it remains essentially the same as it was way back then.
Then I did a lot of on-line browsing for free and linkware graphics, building up my own little library.  I needed these to fulfil my vision of how the homepages and notes pages would work.  I also got permission from Forever Knight fans with photo archives to use some of their screen captures to illustrate my site.
After that, I wrote another page, and another and so on, learning as I went.  I don’t know about practice making perfect; but it certainly leads to improvement.

Aren’t you leaving something out?  Didn’t you first practice writing HTML by using the exercises in the books?
No.   Why should I?  I wasn’t interested in their webpages.  I wanted to get my own written!
        But, of course, for my first attempts I did pick out something that seemed to me to be pretty well the simplest thing that I’d want to do for my site.  The ratings page involves just a couple of nested tables, hexcoded colours, font sizes, and CSS-tweaks on the borders.  Yes, it did take about three hours to get it right—and most of that was spent getting it to run at all.  But, starting this way, I finished up with a webpage that I could actually use on my site.  A practical achievement, in other words.

The format you use takes quite a lot of getting used to.  Why don’t you write regular stories?
Because TV isn’t prose.  If you’ve ever read adaptations of actual movies or TV shows into prose, you’ve probably noticed that the ones that include strictly what was in the script—maybe, if you’re lucky, with the addition of some of the on-screen action—do not make very satisfying prose.  When we read novels and short stories, we expect more detailed description and more introspection.
When prose is adapted for the screen, it is equally unsatisfactory.  If you are accustomed to a story in a prose version, something always seems to be missing when you view it.  Even with the best possible actors, there is no way to convey all of the character’s internal musings, except perhaps with voiceover, which always seems very artifical, even when the same text appears in the original prose.
Yet it is not that prose is the superior narrative format.  Each has its own weaknesses and its own strengths.  Film does a much better job of conveying action.  No adaptation can ever be quite so exciting in that regard.  And prose requires sequentiality:  you cannot simultaneously describe the setting, the costume, the dialogue, and the action in words.  But there is, of course, no problem in having all four on screen together, which speeds things up considerably.  Film is inherently a “tighter” format than prose.  Also, of course, the facial expression and vocal intonation of the character can only imperfectly be conveyed in prose.  Actors—well, good actors, at least—can do a very much better job in that regard.  And the regular characters on Forever Knight were certainly played by good actors.
Forever Knight was a television series.  I wanted more of the original.  Failing that, I wanted more stories as close to the original as possible.  Obviously, I couldn’t actually film new episodes.  But I could adapt the full script format to include as much of what I would have been seeing and hearing as possible, so that—by visualizing and “auralizing”—I could come as close to watching new episodes as humanly possible.  Well, short of CGIing them, anyway.
