The body was too wide. Now it fits screen resolutions starting at 1024px width. It's centered. All Silverlight applications have been modified accordingly. I fixed some layout issues with Firefox and Chrome. Mashooo looking good.

Finally a little great addition: Users are now able to choose to register either through a Mashooo account or OpenID.
