I've been using it since the beginning of November. You can apply here: http://advertising.msn.com/searchadv/PilotForm.asp
That seems to be for an advertiser, not for a publisher though. Do you have a link for the publisher to sign up?
That's what the orginal poster (Mike) was asking about. There is no publisher division of the Adcenter program at this time.
yep, no adCenter for publishers yet. i don't know when it will happen but if you have any ideas or requests let me know and i can pass them along to the folks doing the planning. thanks, adCenter
I see that an adcenter rep has been busy on forums (including DP). So far I have been reading requests for suggestions, not really much more. Has anyone been given some concrete answers from him so far on anything that is coming up and going to improve what GA and YPN have been doing?
