Aged Content Message

This is great little helper! :)

The settings are easy and it does nothing without you configuring it.

If you need more customizations, then you can use filters to further prevent or show the message.

You can style it yourself if you know CSS, but it ships with a generic CSS styling which works in most cases.

Recommended little plugin with a responsive author and a Github repo for issues or PRs. 

Open source can be fun with such great little helper plugins. This is the reason why this directory exists.

Hopefully the "[Discontinued]" text on the Github repo is a mistake ... 

Great little helper - very customizable

Displays a message at the top of single posts published x years ago or earlier, informing about content that may be outdated.
