Publishers who are in the Google Affiliate Network must link their accounts to Google accounts by September 21st, in order to get paid for July 2009 earnings without any delay. An email was sent out to these publishers yesterday, warning of the new requirement.

A copy of the email read:

Not all publishers are eager to link their accounts to a Google Account, but the bottom line is, they have no choice. Google has been doing this with all their acquired properties, so it is the next one to bite the dust.
