It used to be I could find tons of news groups and mailing lists to subscribe to, and I loved participating in them. These days, though, it seems that most of them are dead.

Oh, I can find plenty, of course, but most of them are empty, aside from some script kiddies and people introducing themselves.

Can anyone suggest any good newsgroups or mailing lists? Any and all topics are great, crypto, security, programming...everything. Thanks for your help!
