Well, conlinguistics really. I'm more of an amateur linguist. Not having had a formal education in the subject. But I conlang, and that requires a knowledge of linguistics.
In this section of the site, you can find germaniconlanger's most needed but until now hardest-to-come-by resource: an online list of the Germanic inflexions. Okay, I lie. You can find stuff on the nouns. The rest comes later. Tomorrow, maybe. You can also find a very useful guide for newbies to the CONLANG mailing list: a Conlanger's dictionary, which contains much CONLANG jargon. You're under no obligation to use any of it, but others probably will.
At the moment, you won't find anything on my conlangs, beyond the following brief discriptions.
Finnstek and Finnzsa were the conlangs of the Jungle Crocodiles of Planet Pii. Unfortunately, I seem to have lost a lot of stuff about them. I keep them around mostly because I want to design a couple of fonts for them.
Etábnanni was a reaction to a comment on the artificial languages newsgroup. Someone said that g was always hard on their language, and I got bored of regular orthographies, so I tried to create an irregular one, but ended up getting something regular but complicated instead. The name of the language is pronounced /ra:mnæn/.
Pidse, or more accurately, Ƿıdse, is an auxlang based on Ygyde, another auxlang. It succeeds where Etábnanni fails. The name of the language is rather regularly pronounced /wið@/—and puns on the word 'wither', given that it's a withered form of Ygyde.
Føtisk is my family of west germaniconlangs, and the reason I created the Proto-Germanic Inflexions page. They're the most actively developed langs I have at the moment. The name of the language is cognate to Deutsch and 'Dutch', but is almost arbitrary in that no language with that name has been made yet. I have a Foietisc and plans for an as yet unorthographied language, the name of which is regularly derived from Foietisc and pronounced /ʍetʃ/. Based on some other things I've said, I also have a language whose name is Fœtisk, which I think should continue unchanged in spelling till it becomes /ʍetʃ/.
