This is an event plugin for popular open source Q&A platform, Question2Answer. It stores all edits to posts, allowing users to see what was changed.
Download and extract the files to a subfolder such as
qa-pluginsfolder of your Q2A installation.
Go to Admin > Plugins and click the 'Set up edit history' button.
noindexmeta tag is included on the revisions pages by default, but you can still block the pages with robots.txt if you prefer.
User-agent: * Disallow: /qa/revisions/
Here are a few of the planned features for the future:
- Page showing recent edits.
- Allow moderators to roll back revisions, and possibly delete revisions.
- Access control (e.g. only allow moderators/admins to view revisions).
Most of my code is released under the open source GPLv3 license, and provided with a 'Pay What You Like' approach. Feel free to download and modify the plugins/themes to suit your needs, and I hope you value them enough to make a small donation.
