Adelic This is one of the first conlang project I came across on the internet. I like it a lot. When I read about Adelic in the 9th grade, it made me feel ecouraged to continue my uchronic alternate history projects.
Ardalambion This is your one-stop destintation for all things linguistically Tolkien. Highly recommended.
Artificial Language Lab Rick Harrison is one of those conlangers we all know. This his conlang database. There are some interesting languages here, some that you won't find anywhere else.
Artificial Languages This is a Yahoo! Club I co-founded. Drake and I have been leading this club for nearly two years now, and many amazing language projects have been inspired by the work here.
Chimeria Alexa's (Lessa's) con-country. It was originally a school project. Some interesting political things and mention of an artificial language.
Choba, Jafo, and Oşë Thomas's languages! Thomas is an Artificial Languages goer and a Talossan. The really cool thing about Thomas's languages is that he creates entire language families.
The Conlang Yellow Pages Fun for browsing. I just wish they gave more of a description for each language.
International Auxiliary Languages A great page for IALs... if you're into that type of thing... :)
Kakarak and Scallin Kakarak is not exactly my type of language, though I did read a bit about it when I was beginning to work with Peto. Scallin, on the other hand, is one of my favorite conlang projects; it reminds me a lot of Cepperjoleddicg.
KLI The Klingon Language Institute. I read somewhere that Klingon has more speakers than Cherokee. Anyone know if there's any truth to that? I have three books on the subject myself...
Láadan The Womanlanguage! Most languages are partiocentric; Láadan was designed to be a matriocentric language.
langmaker.com The site for conlangers. The page updates incredibly slowly. I submitted the Cepperjoleddicg link in May of 2000, and it still isn't up.
LEARN NOT TO SPEAK ESPERANTO Jeez, I don't like IALs. This, I thought, was a genius critique of the most notorious International Auxiliary Language.
Mark Rosenfelder's Metaverse Home of Verdurian (an incredibly complete language) and lots of other little neat language and culture pages.
Mead Dragon's Beer Hall This page is... well, partially about linguistics :) Drake is the fearless leader of our Yahoo! club, and he does some interesting things. I think I like Dlatci the most out of all his languages. He's a stickler for regularity.
Talossan Everyone has heard of Talossan! It's a staple of the conlang world, just like Esperanto. I like Talossan a lot, and at one point I considered joining these guys just so I could argue politics and work on the language.
Vaior William Annis's newest lanaguage. It's one of the most complete conlang projects I've seen in a while.. William is a co-founder of Artificial Languages and he is the inventor of Bálabhádh, a project Drake and I are also working on.
