Thanks, Greg. This correlates with what Mike Kenzie was describing to me last night. He said he often does not receive the first of a new topic on OCLUG-Tech or Board mailing lists, but always seems to get the replies. AFAIK I've never experienced it myself, but since you're not the only one I'd say this warrants further investigation. I just don't know how to do it. Of course, as someone posted earlier, the question becomes whether it's feasible/worth it to quickly patch our current system for the moment, or if it's better to just expedite the major hardware and software upgrades we know need to happen anyway. Either way, I only have a portion of the knowledge needed but am willing to assist with the necessary tasks. For those who don't know me, my background is in electronics and computer repair, networking, and some web admin/development (LAMP, installing/maintaining scripts); actively using GNU/Linux since about 2000.

I don't know who to remove from the address list. You might revert to one open maillist. There are some anomalies. _1_ Once in a while, I receive a reminder that I am subscribed to : [oclug] = <oclug [ at ] lists [ dot ] oclug [ dot ] on [ dot ] ca> Recently, seeing a remark that [oclug] is deprecated, I attempted to subscribe to : [OCLUG-Tech] = linux <linux [ at ] lists [ dot ] oclug [ dot ] on [ dot ] ca> I was informed that I am already subscribed, and received an emailed warning that possibly "a bad person" was meddling. (That is a nice thoughtful addition.) _2_ I receive (one copy of) almost all posts sent to both lists. A quick check, late at night, of the archives suggested I do indeed receive all messages, except sometimes the first of a new topic posted to [OCLUG-Tech]. There were so few that I may have lost some to carelessness or the whims of spam checking. I would want to check my records again before anybody spends more than a millesecond on this. _3_ There are two archives, despite all messages (absent glitches) being sent to everybody. If somebody on [oclug] replies to a message posted originally to [OCLUG-Tech], the reply goes (first) to the [oclug] list. Immediately there is an ambiguity : which archive stores the message? It appears (again, minimal checking) that any first message, and any thread which stays on one list, is stored in the corresponding archive. But if a thread crosses lists, subsequent messages are stored in the [OCLUG-Tech] archive regardless to which list that message is sent. I thought I saw a second level ambiguity, however, I could not refind it : if "[OCLUG-Tech]" was removed from the Subject: line, and the message was sent to [oclug] it was stored in the [oclug] archive. This suggests that maybe a common process examines all messages and looks only for "[OCLUG-Tech]". _4_ You probably didn't need all that, perhaps mistaken, detail. I think there should be only one open list, and one archive. Sometime, somebody, bored, and trustworthy, should merge old archives. Greg Lisa wrote: > Thank you Dave, for your help with this.

The difficulty we've had in determining who administers what, and emergency preparedness, for me has served as a disturbing wake-up call.
