Fanfiction.net has quite a few IDoJ stories (https://www.fanfiction.net/tv/I-Dream-of-Jeannie/), including recent ones by some good friends of mine, as well as at least one member here. Y'all ought to check them out and comment (authors love to get comments!)

I haven't written anything over there in a while, though I have posted a magic guide on my deviantArt page (http://kentauros.deviantart.com/art/The-Djinni-Blinkbook-604595938). That's something I wrote up by observation of the show many years before the Internet existed. These days, most would compare it to those lists of superhero powers, but I would not. Magic is not superhero powers, which is usually based on an attempt at science-fiction abilities (mental abilities, in most cases.)

I'm still adding to it, so hopefully people don't judge it with the dismissive "tl;dr" and at least have a look :)

Yup, fan fiction still exists, and more seems to be added to fanfiction.net every day. I haven't written anything recently either -- professional life has been interrupting -- but still exists on our website as well (see signature line).
