Conversant has a cool page type called "Advanced Query Page" which is like a stored procedure (search query) for a discussion group.

I set one up that searches for messages by me with the label "XMas List", sorted by Subject (rather than by date).

I customized the template for the results so it only shows the subject and a link to the message. The default template is much more detailed.

The result: Conversant is maintaining my Christmas List for me!

To add to the list, I post to the discussion group, and tag the message with the "XMas List" label. The rest is done for me.

Sweet.
