no it will not, and i support this idea....
i suppose this could be done by putting in your first.mrc (or whatever you call the script that's loaded in slot 1) something to set %event.text $1- and then in last.mrc echoing that text. Making all your scripts alter %even.text won't be difficult.
Nice idea tho for cross addons (i want on input too, for those nickname completors etc...)
