>The word "launching" also comes to mind. It is interesting how sending off an email or ng post does have that definitive, do-or-don't, "off it goes," "too-late-to-change-your-mind-now" feeling that's associated with the "send" button.
For me, as a tech writer, "launching" means launching applications--a computer button equivalent to a wizard's incantation for invoking forces. Context means a lot, I would say. (In case you hadn't guessed, I love words, word play, and imagery.)
