furthermore, if you receive an accidental reply all, please also do not reply all again to tell that one person they've made a mistake.
here's a simple way to figure out if you're doing it right:
does the "to:" box say a single person's address? if so, you're doing it right.
does the "to:" box say multiple addresses, or the address of the listserv itself? if so, you're doing it wrong, and i will shoot you in the face if you hit "send".
kthx you may return to your daily life now.
