I wanted to use the playground  but it and other aikiwiki pages seem to be in read only mode. I don't see an edit button and when I switch to "Show Page Source" mode it says "This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong" across the top. Below the page source box it says "Logged in as: Marc Kupper wiki/playground.txt • Last modified: July 19, 2006, 5:00 pm." The date/time seem to get updated (to the nearest hour) but I can't make changes.
