When I first came in this morning:

+ Visual Foxpro
+ Chatter

After opening the Chatter forum:

        Re: Darwin Awards Mike Helland 05/03/2006 18:23:43 
        (and every other "Darwin" message displayed)

        Re: Due to an energy crisis... Mike Beane 05/03/2006 10:50:31 
        (and every other "Energy" message displayed)
    (and every other thread and message under Chatter displayed in a very large treeview)

Do you not understand that someone would rather just see this instead?

Is this what you see? If so, then tell me how to set it up. Otherwise, then it is somewhat of an all-or-nothing regarding the expand and collapse functionality.
