Two days ago, we reported that adCenter has a new logo. It looks like Microsoft is not stopping there in terms of giving adCenter new enhancements. These include:

Campaign Management: you can now pause/resume ads/keywords. There’s more geo-targeting options, and performance reporting has gotten enhanced.
Editorial Improvements: You’ll know much sooner why your ad has not been approved and get inline notifications on exceeding limits imposed by the system.
User Management: You can now add more than one user!
Content Ads: In the US only, you can get keyword suggestions/performance estimates for Content Ads

Initial feedback is that this is good stuff, but many wonder when adCenter will catch up to AdWords.
