Lines: 17 No, the message tree is something that exists independent of your individual machine. The root is still the root no matter if it has expired off every machine on the net. To chain up through parents using information on your own machine, only the immediate parent is required -- unless you want to chain past expired articles to their parents that somehow didn't expire. (You could have expire, when deleting a message and not deleting the parent, leave the parent around in the database) The full tree is needed to kill it, ask for it or work with parts of it. At the least, 'important' nodes are needed. I would define important nodes as the root, and any nodes at which the subject truly changed. Sadly we can never perfectly spot the latter. -- Brad Templeton, Looking Glass Software Ltd. -- Waterloo, Ontario 519/884-7473
