Tutorial for Authoring Kit
 

So it looks like this part of the forum was started in 2008. Yet the HLKitWiki is still missing ([TBD]) like 80%(?) of its content...
Has this been relocated somewhere else or is it just not going to be done?

Honestly, probably the latter. Lone Wolf is a small company, and the Authoring Kit doesn't make them a ton of money. If I poked around a bit more, I could probably find the statement, but the wiki is basically a "when we have spare time" and that's in short supply. That said, both Aaron and Mathias drop in frequently to answer questions, and you can always ask questions of the other users.

Do you have anything specific you're trying to figure out?
