Thank you for making the point. To be even more precise (and I know you know this was well, just spelling it out for the archive): Changing the state of a thread (change the subject, split the thread, lock or delete it) is easier in *any* medium where you control the central database in contrast to a system which has multiple decentralized ones (if you call mailbox of each individual recipient a "database"). >> How this would translate to the mail interface (my guess: it doesn't) >> is > I have to agree. I know MS Exchange has a "recall email" function, which can create confusion among its users, for example when one instance allows it and another does not. Usenet also has Cancel and Supersede control messages, which have in the past been (ab)used to various degrees, up to the fact that today most sites don't honor them, whereas some do, but only when used with the correct Cancel-Key in the header, a mechanism not all clients are able to use. In the end: it is a mess. Grüße, S! -- Sigmentation fault. Core dumped.
