I have updated the MicroWiki code to fix a couple of bugs and add move and delete capabilities.
For those who are unfamiliar with MicroWiki, you can use it with my EzStatic plugin (or by itself) to create a wiki inside your WordPress layout that is independent from the posts/pages structure of WordPress. You can choose to use WordPress authentication (only WordPress authors on your blog can modify the wiki), integrated authentication (where every user has a password that is maintained by MicroWiki), or no authentication (like most vanilla wikis). It’s a nice and simple one-file solution if you’re looking to add user-contributed documentation to your blog. Check out my installation of MicroWiki.
