A forum posting I made back on the MSN adCentre discussion forums about adCentre accredited professionals or as Microsoft would call it an MCP (Microsoft Certified Professional).

A Microsoft employee replied that something would be coming in the late Summer and it has appeared that there is something underway named "adExcellence". Unfortunately this appears to be a private Beta for American customers.

Has anyone heard of a UK/International version coming soon?

This will definitely be launched at some stage for the UK but there are no specific dates yet. I will inform you once I know more.
