Hey guys, I made this for work so I can't really host it anywhere... I will paste it into here as its a small code.

I must admit I had a few problems getting to grips with the API, so some code in there is unnecessary but atleast it works!

Description:

The user interface will allow you to add HTML code to be displayed according to country, currently it had HTML for U.S. U.K. and Global.

Note: This is not a serious plugin, and will probably NEVER be updated!
