There isn't really a process to it. For starters I would create a tutorial database in the forum that's similar to the ASL Scripts Database topic, and build up a categorized list of tutorials. Like with the scripts, as many tutorials as possible would be hosted on my server. Then eventually if Steve ever gives me the time of day, I'll submit an html version of the database for him to put on the main tutorials page, and we'll see what happens from there (some day he might put up the scripts database web page he requested from me...).
The most important part is that the tutorials will be listed and categorized in this forum at least, and updated constantly as you guys make new ones.
So if you make a html-based tutorial, video tutorial, etc., and would like it hosted, just email it to me and I'll put it up. This will save me the time of having to grab it and host it later on anyways. The reason why it's important for it to be hosted on a dedicated webhost is because of the yahoo! geocities example. There were a lot of tutorials hosted by geocities, but then geocities was terminated. So where'd those tutorials go, eh?
If you don't want to deal with html or whatever but still want to make a traditional tutorial, you can also make it as a topic in the general anim8or board using the forum's markup to format the tutorial how you'd like. Just email me the images beforehand so I can host them, or upload them to imageshack so I can come in later and replace the images with ones hosted on my server.
Format them however you like. The more thought you put into the design of the tutorial, the better it'll be understood by the users who look at them.
If I ever find that secret cache of free time, I might make a few tutorials as well
Probably a detailed uvmapping one since I have yet to see a really good one that teaches the best way to do it...
