I saw user1 and user2 area in mambo. And that gives header, left, center, right, footer plus 2 more layout area

Having these extra area will enable theme designer to make flexible layouts, hence more suitable for enterprise market. Otherwise all sites are looking pretty much same in layout no matter what they use - nuke, pn or xoops.

I love XOOPS - mainly because it is neat and it talks oops Wish XOOPS can do what mambo does...
