Shortnr Light
Plugin Description:
Find it in the Plugins tab, enter the URL you want shortened, and hit Shortn!
This is a simple derivative of my actual URL shortening project, just to put something out here.
It currently requires fancy URLs to be turned on. Then again, if your server can’t do that you probably shouldn’t be shortening your own URLs either way.
Install Instructions:
Unzip the file and drop the .php file in your plugins folder.
