[Mediawiki-l] User Variable for Use in Templates

[Stéphane Thibault]

Hey guys, here's what I'm trying to do.

I'm setting up a MediaWiki website for a scientific association and  
instead of relying only on collaborative writing, it's also important  
that members be allowed to write "signed" articles on a subject that  
may already exist.

What I'd like to do is include a string in the  
[[MediaWiki:Nogomatch]] that would allow the user to create the  
desired article after a failed search, redirecting him to this page:

User:Username/Article

The original article page would then act as a disambiguation page  
listing all articles written on a particular topic.

It should be simple enough but I just can't find the proper variable  
to use for the username in my template. I looked at theses pages:

http://meta.wikimedia.org/wiki/Help:Variable
http://meta.wikimedia.org/wiki/Help:Magic_words

but couldn't find what I'm looking for. Any hints? Is there a built  
in template maybe for "wgUser"? Or maybe even a simpler way to  
achieve this goal?

I originally posted my question over here if anyone's interested on  
this topic:
