The pubCenter Spring Upgrade is nearly complete, and we're pleased to fill you in on the new features you'll see when you sign in over the weekend. These new features are designed to:

· Create higher demand and increase yield for our publishers by allowing advertisers to bid directly on your site.

· Expand your access to advertisers using animated GIF and Flash ad formats.

· Help you optimize performance by comparing different ad units in the same page space.

· Improve usability with new help features.

Look for more detailed blog posts about these features in the coming days.

We are continuing to build a new marketplace for both publishers and advertisers with the goal of helping publishers achieve competitive yield and helping advertisers see better performance from their ads.  This upgrade is another step in that direction. 

If you are interested in beta testing, or know some US-based web site owners who would like to test the beta, sign-up here: http://advertising.microsoft.com/publisher 

We are looking forward to hearing what you think about our improvements and, if you haven’t done so already follow us on Twitter to keep up with the latest pubCenter news, tips and tricks.
