Adding to Gnome Menus

[Hoover Mark A AISC CONT <HooverMA SUPSHIP NAVY MIL>]

Does anybody have a link to information for adding a sub-menu + application
items to the Application menu on the Gnome menu bar?  I've spent most of the
day with Google trying to find out how to do this.  RedHat's pages have
information on removing items, but not on adding them.  I've found some
information which said to create a ~/.gnome2/vfolder directory, but that
doesn't seem to work....:(
