I assume it used to be a cool thing, back in -67 to have a post office,
nowadays we have the 'mail' command, , or probably its just a typo (M=K)
Would be neat to make it a Brownie Post module, so I can send brownie posts to
folks easily. And those brownies should carry registered mail too...I want a
read receipt, damnit! (ok, it's been a few months since I sent brownie
mail...)
