This plugin adds some content to the bottom of every post. That is all. No extra crap.
This plugin does one thing, and that thing is to add some content to the end of each of your posts. This change happens on the fly, so if you deactivate or uninstall this plugin, the feature goes away.
I created this plugin because the others are too complex. There are few plugins that claim to add a footer to each of your posts. Some of them work, and all of them have way too many features.
