Thanks for the link, Cris! I'm looking at that site and some others.

Does anyone know the term for a menu that moves with the page? Lets say, for example, that the bar at the top of this forum with "Forum List, My Stuff, User List, etc" would move when you scrolled, but then stick at the very top of the browser window as you scrolled further down the page. The only way I can describe it is a "floating menu" but I don't know if that's what web designers call it... I'll try to find an example on some site...
