While I'll be put out if I ever catch anyone using
ichimunki on another site or anywhere really. I think I'd only want it registered on sites I actually use (like Slashdot or Perl Monks). For some reason I haven't registered it on Kuro5hin or E2 and I'd have to wonder if it's available as an AIM screen name (I've probably registered it and forgotten the password). I suppose to be safe I should grab ichimunki@hotmail.com and ichimunki@yahoo.com and any other thing like that where someone could be impersonating me.
I've already got it as ichimunki.com, but AFAIK no one's gone after .net or .org. Names on the internet are always going to be a problem. I think my favorite is when I get mail for the .net or .org versions of a domain I have as .com.
Here's an idea I'd almost rather see, a Tk-script that lets me edit a posting, spell-check it, then creates a GPG digital signature for it, and appends that to the message so I can cut and paste into the input box and be certain that imposters cannot imitate me without my private key. (Is this even possible? I still don't quite get how public key encryption works.)
