This is very interesting to know that adCenter team is getting feedback from the advertisers and thereby improving features to give you more control over over targeting, bidding and distribution of the several advertising campaigns.
The adCenter provides Feedback Form that allows the advertisers to fill up their feedback that will help adCenter team to improve advertising features.
Further, the adCenter offers Feedback & Feature Request Thread on its discussion forums, which enables the advertisers to share their opinions and see other's views as well.
All these steps have been taken to enhance and improve different advertising campaigns. As mentioned in the blog of Carolyn Miller, feedbacks and requests from advertisers will be seen by the appropriate teams at Microsoft and immediate action will be taken.
According to the adCenter team, people sharing their feedback and requests need to mention the reason as to why certain features are important for them, because it helps the team to evaluate good ideas.
