That is great advice, writermom. I just want to add that if you don't have an existing relationship with the editor, don't be surprised if you don't hear back at all. This can be frustrating, especially if you want to pitch the idea to another publication (be careful with pitching to several places at once... can get you in trouble), however, these editors are inundated with emails. Not to discourage you, just to say you should quickly develop a thick skin if you don't already have one
