Replying to that list simply sends mail to me; you still send mail to
extropians to post.  It's not a separate discussion group -- and given
that the recipients can't even respond to a test-request without
individual attention, I don't think it's going to become one.  Just a
one-way filtered digest.

It struck me last night that my list is rather conservative, at least
compared with Rapture of the Future/Anarchy Now!/Singularity Rulez
people.  In the mainstream sophisticates are known for entertaining 
new ideas; in radical environs they keep old ones...

"No, life is not fair.  Not intrinsically.  It's something we can try to
make it, though.  A goal we can aim for.  You can choose to do so, or
not.  We have.  I'm sorry you find us so repulsive for that."
