Sparta: In this particular case I don't think it's a very big deal but generally we should be very careful with automatic messages. And, generally speakin, if beginner asks advanced users to write a script, the "moral responsibility"
of an advanced user is to provide as "legal" script as possible because beginner may be unaware of such issues. I know that IRC is usually more like anarchy than lawful society, but still...
But no big deal here.
PS. Irc-servers should have better notify. They should handle full nick!user@host addresses and report changes in "away" status. Maybe one day I'll script one if servers do not develop.
