controller structure

hi all,

My site contains several controllers (agenda, blog, album...).

I now want to build the entry point of the site where I want to show
info from agenda, blog and albumcontroller.

I have some doubts on how to do this in a rails way. Do I build a new
controller for the entry that itself uses he code of the other
controllers (eg: show_agenda_entries)? How can I access the code in
one controller from another controller?
