I have enjoyed my brief sojourn as a subscriber to this discussion list. Occasionally, I have even posted the odd message intended to help someone. Regrettably, I have had to send an unsubscribe request, due to the large volume of postings. Many of these involve discussions of issues such as Dutch humour which could not, even with great charity, be considered remotely relevant to PIC microcontrollers. Sadly, this is a prevalent problem throughout the Internet; noise levels just keep rising. Those of you who do post such blatantly off-topic issues should consider the day *you* would like some help. All the people who *really* know the answers will have long gone, leaving you to converse endlessly on the topic of Dutch humour, perhaps, but certainly not PIC microcontrollers. I do not know if the answer to this global babble is moderated lists, or what. Splitting lists into sub-topics fails because often it's not clear who might be interested. May I suggest, as an interim measure, the method adopted by radio amateurs. Every city has one or more 'repeaters'. These accept incoming calls on a particular frequency, amplify them and re-transmit on an alternate frequency. It is etiquette to call CQ (who's there, in essence) on the repeater input channel, and once contact has been made with one or more people, move to a mutually-agreed frequency, thus leaving the repeater free once more. If you want to move off-topic, can't you do something similar?. In which case, can we have an off-topic list as well; those who like to chat with others who share an interest in PICs (say) can post to this list. For example:- From: Frodo To: discussion list I'm having a problem with the 16C84.... blah blah blah.. btw: that reminds me of a great joke about Dutch humour. I'll post to OT on it. Or From: Bilbo To: discussion list I need help finding some Philips components. I'll post details to OT; any replies to OT please. IMHO this will reduce noise levels substantially; for example, the long thread on atmospheric electric charges could be pursued at leisure OT. This may well interest some of us; it would be our choice, though, as to whether we bothered to pursue the topic. Technically, *this* post, having raised the topic, would then say Discussions on this to OT, please. so if you feel I personally should be pickled in boiling oil for being such an asshole, you can do so without subjecting the rest of the group to the ordeal, yet you are still talking to the same potential audience. Is this practical?
