By default, anonymous users cannot edit the wiki. This plugin allows anonymous web users, who have not signed in, to edit any page in the wiki by default.
Please think twice before enabling this plugin. If your wiki is accessible to the internet, it will be subject to spamming if this plugin is enabled. Such spam is not only a pain to deal with, but it bloats the revision control history of your wiki.
The plugin has a configuration setting,
PageSpec can be used to allow anonymous editing of matching pages.
If you're using the comments plugin, you can allow anonymous comments to be posted by setting:
anonok_pagespec => "postcomment(*)"
