This plugin is to make custom footers that have been added to Discourse forums stick to the
bottom of the 'page'. It defaults to targeting footers with an ID of #sticky-footer.
The target footer ID can be chaged in the plugin's settings.
Follow the Install a Plugin howto, using
git clone https://github.com/scossar/discourse-sticky-footer as the plugin command.
Once you've installed it, review the settings under plugins in the admin section of your forum.
Create a footer by adding markup to the Footer section of Admin>Customize>CSS/HTML.
Give your footer an id of #sticky-footer.
