Two, actually - first, for the most stories submitted in one day (that is, two - "Golden Opportunity" and, the fresh off the word processor "House Hunting"), and then for most stories under consideration at one time (four - On Spec did receive my story, and it's still under consideration, Clarkesworld Magazine, Baen's Universe, and now Strange Horizons). Hurrah! Maturing as a writer!
Yes, I chose Strange Horizons again, but I've been reading it with fair regularity and I'm really enjoying it, and I think "House Hunting" would be a good fit. I'm kinda in love with "House Hunting," I currently think it's the best thing I've written so far, and I've never reread it and not thought, "Damn, I'm good."
I mean, I've felt that way about all my stories at some point, or else I never would have submitted them to magazines in the first place. But then after I've submitted them I think they're awful or immature and how embarrassing it will be for the editors to read it - but so far that hasn't happened with "House Hunting" yet.
I did include a cover letter this time, the standard issue for me - you know, the one where I say I'm a Senior reviewer for Green Man Review and yes, my fantasy novella DID get published by a professional magazine. I'd like to think it makes a difference, but I guess it all depends on the editor.
