The unabomber was Ted Kazcynski. McVeigh was responsible for Oklahoma City. Just a small quibble. Both were nuts.
About nicks, I've been using this one for over a decade, and had lots of others before on the BBS scene from 1980 on. Since my previous nicks didn't always fit in a login, I picked a word and a sig that would go together: "Don't cross me and I won't cross you.", voila, Cruciform
I had a lot of people ask me if I'd ever read Hyperion by Dan Simmons when they'd see the name so eventually I checked the books out. Strange and interesting. I have to get the whole series eventually. Turns out that the cruciform in the books is a weapon with regenerative powers that it uses on those afflicted by it.
