There have been a growing number of defacements to the tkinter wiki. In order to create a small barrier to these defacements, I have changed the configuration so that authors must log in (by visiting the "UserPreferences" link shown at the top of each page) before editing pages. I've done my best to clean up after the defacements (links to sites that are at best unrelated to tkinter) including the removal of the defaced versions of the page, since search engines might even index those pages. If you see a defaced page, please revert it to the undefaced version and leave something obvious in the change comment so I can remove the archived defaced version too. Not so sure I like wikis anymore, Jeff
