Implementing a ad service
This is a test for a ad service.
I thought is was hard to implement an ad service. But it is not. Just a few copy and paste actions at the right places.
 Well initially it was easy but the video is not working now. That's quite annoying. Maybe it is because I use the files from Jeroen Wijering his site. If they are moved or that site is unavailable it will break.
So I changed this by grabbing the files from my own site.
