Real Name: Mark Krenz
I run several mediawiki wikis and have written an extension called PageCreateOrder that displays a list of all the articles on the wiki in the order that they were created. This was useful for Bloomingpedia because we wanted to see what the Nth article was for our milestones page. I'm working on cleaning it up so that it can be included on the extensions listing page. If you need it immediately, you can email me at mark _change this to an at sign_ suso _dot_ org.
I've also participated in a wiki panel discussion at Indiana University's Unix Systems Support Group. The discussion had a good turnout and shows that there is a lot of interest across the board in wiki technology.
