No worries, I didn't think otherwise:-) In a full class (multi day) I try to give as much credit as I can, if only so people can learn the history of something (which Todd will tell you I'm somewhat fanatical about). On the internet, I just hate typing, so I sometimes leave things out for brevity.
On that note, if I ever seem to be wrong about something, it's only because I was tired of typing, not actually wrong;-)
