You can also post your questions on Stack Overflow

[Jose Alcérreca (AdSense API Team)]

We will be monitoring stackoverflow.com for AdSense API questions from now on. We created the adsense-api tag for both the AdSense Management API and the AdSense Host API. 

If you want to use this channel to post a question, go to http://stackoverflow.com/questions/ask

We will still use this forum for important announcements and support.

Cheers,

Jose
