A prototype for an inline commenting system where a user after landing to a wiki article can make useful comments on some part of the text. This uses the OKFN technology available under the MIT License https://github.com/okfn/annotator/blob/master/LICENSE which allows user to annotate text.
Install it by adding require_once("$IP/extensions/Prototyping-inline-comments/Annotator.php"); to your Localsettings.php
