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, select Beta for American customers only.
Hello All The program is called adExcellence and you can sign up for an invite to the beta here: http://adexcellence.com/adEx/PilotRequest.aspx At the moment it is a US beta but we're working on getting a pilot started in the UK by the end of the year. Thanks for you interest, we'll keep you updated here and on the adCenter Blog. Cheers adCenterEU
