Skill Challenge articles on DDI: where are they?

[Dormammu]

I have seen a few people reference articles discussing how to run Skill Challenges. Some people have said they're in Dragon and recently someone said there were some in Dungeon. The only one I can find is a 3-page article in Dragon #369 by Mike Mearls, and even this one is "to be continued" without any new article in 370 or (so far) 371.

Any others out there?

This is what I found:
First Article (http://www.wizards.com/default.asp?x=dnd/drfe/20081107)

Second Article (http://www.wizards.com/default.asp?x=dnd/dursc/20081203)

And the most recent (http://www.wizards.com/default.asp?x=dnd/dursc/20090114)

I'm not sure if they are free or if you need a DDI subscription to view them.
And this is all that I know of, if there are more detailing ones, they're probably in the WotC forums.

Confusingly, the initial article was Dragon content, but the ongoing series appears to be a Dungeon thing.

You know what would be nifty? If they got their act together enough to publish author-specific or topic-specific feeds for DDI articles.

But this is WotC. Never happen.
