How do I create 2 (or more) (MobileMe) web galleries using iPhoto 08. Current gallery is (for example) How do I create

I have read: "Yes, you can create multiple galleries, just publish each one in turn. It will use the name of the Album to title the Gallery."

However, selecting photos in iPhoto (or Aperture) and using Share...MobileMe *always* publishes to existing gallery []

I want to publish new gallery to my MobileMe account with new name (say, jamararts) using iPhoto (or Aperture) and photos already in iPhoto (or Aperture) library.

I emphasize that I mean seperate and distinct galleries - not multiple albums in the same gallery.

How do I do this - suggestion of iPhoto steps would be helpful.
