How can I install the confluence-mentions-plugin if I can't find it?

Attempted Resolution:

Tried to install the confluence-mentions-plugin via the Marketplace.

Actual Problem: 

Contrary to the documentation on the User Mentions documentation page the confluence-mentions-plugin cannot be found on the Atlassian Marketplace.

Does anyone know where can I find the user mention plugin so I can enable it for my instance?

You are looking at only user-installed plugins. Change the pull-down so you see System Add-ons, and you should find the plugin you are looking for.

Ugh. *facepalm* I spent so much time writing the question too! Thanks for the save. The plugin was disabled. Such a rookie move.

I knew because I've made the same mistake :).

Beers on me if you're ever in Victoria, Canada then :)

LOL. That's a deal.
