An extension to endorse someone for everything on LinkedIn.
Upon going to your friend/boss/enemy's LinkedIn page, this applet will provide a button to endorse them for every skill they have, to the level that you believe that they merit, and include your relationship working with them.
No one should use it ever, but that's never been a reason to stop something from existing.
When active, it will appear as a lit up medal in the top right corner with the rest of your add ons. Click on it to engage the power.
