Well, here's my updated list: group.name@news.demon.co.uk group.name@news.cs.indiana.edu group.name@bull.com group.name@cass.ma02.bull.com group.name@undergrad.math.uwaterloo.ca group.name@magnus.acs.ohio-state.edu group.name@ccs.uwo.ca group.name@julian.uwo.ca group.name.usenet@decwrl.dec.com I took out cs.utexas.edu; I've had a lot of trouble with that one losing posts. They don't bounce, and they don't get posted, they just disappear. After reading a lot of posts on alt.test, I found the ones listed above. If you know of any more, send me mail! Also, you can use charm.magnus.ohio-state.edu, beauty.magnus, top, bottom... they're quarks! uwo.ca by itself doesn't work, you must use ccs or julian.

I don't know about these, unless you meant Eric/Sameer's remailer.
