I like Glenn's idea above. Please warn us if you are willing to do it and then just delete /home/majordomo/lists/arachne.
But if no one wants the mailing list, why there is still so significant traffic going to arachne-digest every day ? (well, I am not reading it any more... but arachne-digest appear in my INBOX quite often... still I don't have idea how the spam can get in, I deleted most of e-mails in wizards list, the originating addresses are not subscribed... it's weird...)
M.P.
