If I understood well, the HydrogenAudio knowledge base is a webpage to which anyone can contribute.

It would be useful to give a short "how to" about it.

I found the two first steps :
1 - Register
2 - Learn the formatting language at http://docutils.sourceforge.net/docs/rst/quickref.html

But I miss the next ones :

3 - How to create a new article ? Must it be posted in a temp directory and reviewed by an administrator ?
4 - Is there a list of the WikiWords ?

I made this guide to the formatting:
http://doc.hydrogenaudio.org/wikis/hydroge...itingGuidelines

3.: you have to create a link on another page. if you write [AAC] etc. you will get
"AAC?" on the page and when you click the ? you will be making the new page.
If you create links the other ways listed in my guide they appear as normal links but if page is empty you are prompted to make it (wanna create this page?).

4.: not really. this comes closest: http://doc.hydrogenaudio.org/wikis/hydroge...o/RecentChanges

Btw.: you can always play around with the formatting here:
http://doc.hydrogenaudio.org/wikis/hydroge...enaudio/SandBox

Thank you !
Creating the link first and then the page was the trickiest part

Also note there is a dedicated forum for discussing the wiki:

D'oh !
Stupid newbie mistake (and the question was already answered...).
