As one who saw the value of SDLU both as a venting place and a place for 
serious discussion, I'm sad about its demise, but I somewhat understand the 
motivation.

As far as I understand the mailop policy, venting has no place here, and I do 
agree that it's not very productive, so thanks, Graeme, for getting discussions 
on track when they are on the verge of derailing.

That said, I would very much like rational discussion of spam and our options 
of keeping it out of our users inboxes. Finger pointing is sometimes necessary 
as the organizations involved are at least partially part of the problem, but 
it shouldn't dominate the threads.

Is this something that can be done under the umbrella of this mailing list, or 
will spam related discussion be considered off-topic? In that case, we might 
need a successor to the SDLU mailing list, and people who are willing to manage 
it - my spare time and my willingness to cope with all kinds of bulls*** is 
certainly too limited.

Cheers,
Hans-Martin
