I would like to know how he is doing the "Create a Page in The Wiki" module.. His forums gives a small hint, but nothing more...
Quote from the forum:
It's a little module - and surprisingly simple. To add a page to the Wiki you redirect with the page name as a parameter (watch the URL when you create one). So the module simply allows the user to enter a string as the page name and redirects with it as a parameter.

Hope that helps.

and he later goes on to say:
would you like a video tutorial created showing how the "Create a Page in the Wiki" module is made? The source will also be provided for download.

and no video was done, at least that I could find.

I haven't developed a true installable module, but if you have ListX from BI4CE, I have made a configuration to create a new wiki topic that is posted in the ListX samples forum at dnn.bi4ce.com.
