Here are just a few links that I find myself visiting frequently. If any of these links end up broken, please tell me, as I have no control over these links beyond the fact that I put them up here. The contents of these sites are up to their own maintainers.
The Legacy of Timeless Beauty ASFR fiction, recommended by the site designer and one of my lovely editors who is very much into the robot fetish. If she recommends it, it definitely has a spark worth investigating.
MC Stories The Erotic Mind Control Story Archive is simply put the one stop shop for everything erotically mind control that isn't fan fiction or ripe with celebrities (though there are exceptions). This site is likely the most well put together story site anywhere. That color of green that fills every background makes me squirm whenever I see it in real life. If you enjoy any of my work, MCStories is a site for you.
Nifty.org Though I have actually not been to this site for ages it is what started my interest in erotic fiction. This is also the place I first read "Hypnotic Embrace" by Serene Cherry and "Hypnotic Roommates". Without this site I would never have found my way to MCStories, and though not all of the stories are of especially high quality it's a nifty (pun intended) site to find some non-fetish erotica if you're in a truly bizarre mood, or other fetishes than MC if you're just not in the mood for spirals...
Eri's DeviantART Those of you who read the Blot know Eri. Here is where you can find glimpses of her artwork! You owe it to yourself to look. Look!
Bunny's Hideout The personal art site of the infamous Bunny Lola! If you enjoy her art style you should definitely see about grabbing up a commission - it'd be worth every penny.
Angie (Pandora's) DeviantART Host to lots of lovely images, Angie is the creator of Pandora and the original artist for Silver Girl. Be sure to give her a glance if you like anything MC - you won't regret it!
Sue Chan's hypno site! It's embarrassing that this didn't go up with the first mess of links! Sue-Chan is a wonderful artist who I think everyone in the hypno community should or does know. Even when updates were on the fritz I checked at least three times a month. Her art is wonderful, and she's a sweetie to boot... If you aren't clicking this link, I hope it's only because you've already been there recently!
Lady Jenifahr Though I abhor most hypnodommes that even skirt the edge of "professional", Jenifahr is a personal friend. Her files won't be calling you a worm, or filling her checking account. A sweet woman, and a decent 'tist.
Lady Julia A Domme recommended by a friend oriented towards the F/m for the male fans of my work out there! Her safety net file comes well recommended. Another skilled 'tist who from what I hear will neither degrade nor bankrupt. Huzzah!
HypnoThoughts A hypnotic community site that isn't a forum! Think Facebook without the inherent evil, or MySpace without the suck. You can find me there under my real name, Carin McLeoud.
The Green Dragon: MC Edition Revamped after a lovely hacker killed the original site, this version of the old Red Dragon game is based on mind control. Much like the MUDs of yore, this game is a level grind destroy things and then start over extraordinaire. It's lots of fun, so sign up now!
Hypnopics Collective Some of my art is exclusively hosted here - the one and only Collective! Home to lovely art from names from the Archive you'll recognize like Tabico, and some you won't just as skillful, for visual hypnoporn, I haven't found a better site.
The Way Back Machine Archive.org serves lots of purposes, but most incredibly it is the best way to find stories from sites now lost to the flow of intertime. Go there, punch in the emcsa's addy, and you can find stories from lost authors such as Sara H, miketheFable's previous work, and so forth! If there were an "essential emc pack" this would be included in the collector's edition!
Dictionary.com A free dictionary and thesaurus. I likely could stand to use this site more often . . . This site is as highly recommended as Wikipedia, and it doesn't have the user created issues. Fun for the whole family. Warning: Dictionary.com contains small parts and should be kept out of the hands of children under the age of three. Dictionary.com may or may not contain words. Use at own risk.
Wikipedia Say what you will about some of the articles, or the site overall, but I love Wikipedia! Easy to navigate and fun to browse you can be inspired to write fifty million stories if you end up following the right set of links. Just type in anything, that you know about or don't, and you'll probably learn something new. Granted, there is likely a chance some of the information is wrong, but even still it's definitely a fun little game to see how long you can follow one subject around.
