Can you give us some examples of places > where compact representations are really essential? Well, anywhere, basically. You enter a group. The server says that the available articles are 50000-60000. You have a list of, er, ids. How many articles should you fetch if the user wants all unread articles? You want to mark the unseen messages as unseen. Keep a list of all seen ids? Etc. Integers are small and collapsible. IDs are not. -- (domestic pets only, the antidote for overdose, milk.) larsi@gnus.org * Lars Magne Ingebrigtsen
