deprecated: you could also use Shendal's Perl/Tk Newest Nodes client, which uses my PerlMonks modules to provide a threaded interface, which remembers which nodes you have seen, and offers mechanisms for marking whole threads read or unread. It does not have a "subscription" mechanism like the one in mirod's page, but it makes it easy to see which threads have unread messages (because it only shows threads with unread messages).
