[SOLVED] - New page button, for pg not found

[jwzumwalt]

Is there a way to have a 404 page not found, know what page was being attempted and have a button that offers to create a new page with that name?

Media Wiki does this, and I would like to do this, if it is possible.

There is no built in functionality for this, but you can create plugin.
