Anything I say in a general IC post can be considered to be public information unless someone chooses to hide it. No need for IC echos just to spread narration.
However, any response to an OOC post, like knowledge skill tests, is considered private knowledge until it's shared in the IC thread.
By the way, I'm assuming the order involves Machete scouting at point, and Devoted holding the rear in order to keep everyone in sight for counterspelling purposes. This shouldn't matter much, but I like to keep a strong sense of the physical layout.
