Last week, Ad.com launched a self-service tool dubbed PubAccess for small Web publishers to sell and manage ads on their sites.
The launch of the manual tool comes amid reports that Ad.com is in the process of cutting its sales force in half at the behest of Clarizio, who recently transitioned from president of Ad.com to run AOL's broader ad-network group, Platform A.
