Multiuser is not my thing, but can't you just make a linkblog for every user and allow them to do with it whatever they want (and allowing them only on their linkblog). It doesn't sound difficult to append (or prepend) their list with a general list from the organisation.

Just some thoughts.

Good luck

afwas,

not one of my smarter moments. all of these permissions were a bit overwhelming. i didn't even think about keeping it simple.

thanks

But you often do have interesting posts. This multiblogging multiuser fuzz creates food for thought and headache like symptoms.

Have fun
