Cruising for an editor? A bit of etiquette...
Common sense, above all, should be the watch word. You aren't exactly trying to get a job interview as the CEO of Diamler-Chrysler, so the p's and q's aren't life and death important. You are, however, trying to get a stranger with some knowledge on the subject to look at your story and tell you what they think. You don't want to make this person feel hostile toward you, or think you're rude right off the bat either. Since Miss Manners isn't likely to stick her etiquette minded nose into it, a short list of "guidelines" might be of use to first time, or even 40th time, story submitters.
There is only one set in stone rule. Use your common sense. Some of us have to dig deep to find it, but I'm sure it's in there. Somewhere. 1. Some editors preferred to be queried first. Some don't mind receiving a story and a thanks for your time email. Some might. It's best to query first. Some editors don't have a full box, some don't have time. I've talked with several and opinions on this vary. It's better to be safe than sorry and to err on the side of politeness.
2. Don't assume the editor has the same word processor you do. Some editors use off the wall things, like me. I use Word Perfect. That means I can't read your file. You may be using a Mac and your editor may have windows. In that case, you'll have to paste into an email. Usually saving in rich text format helps.
