If someone wrote about storage and also mentioned 'gui' that person, according to your suggestion, should post to two lists and if they explained, at the same time, how they deployed it, 3 lists instead of one ? This inevitably means readers could seem multiple postings, although in different lists, for the same topic and if responding should they post 2 or 3 identical replies - one to each list containing the posting ? Your idea could be modified to including on the subject line a one-word prefix for the topic. For example 'Storage: ......' I concur with the others who thought OT traffic should be marked 'OT' on the subject line and filtered out. Meanwhile retaining one Centos Users list. -- With best regards, Paul. England, EU.
