Hello.
I want to display the list of "document workspace sites" which each
user is member of.

This is the workflow I want implement:
I create a document workspace (let's call it Doc1) starting from a
document in a document library or directly from word 2003, then I add a
certain number of members to the Doc1 members' list. The Doc1 site is
correctly created and all Doc1 members receive the e-mail containing
the link to the Doc1 site.
Now, the question is: where Doc1 members can find the link to the Doc1
site whithin the portal? Can these members have a list containing the
links to all the document workspace sites which they are member of or
do they have to manually maintain their links to workspace sites? Is
there a web part which shows this list?
I expected to find these list implemented in "my workspace sites" or in
"shared workspace sites" web parts (in the user's "My Site") but when I
create the workspace site they remain empty.

I can't find any discussion about it and that make me think I'm getting
lost in a glass of water...

Really thank for any help.

Luca

P.S. I'm working with sharepoint portal server 2003.
