Simultaneous Submissions?

I am not sure I care for the idea of simultaneous submissions. I can see why they're a convenience to the writer, but now that I'm a big-city editor (Ha!) I'm finding the whole concept to be a pain in the ass. Not sure yet if this means I should ban them entirely (not that people would listen) or stay with the current policy which is Simultaneous Subs are strongly discouraged.

Literary types, do you think the submission numbers would go way down if I insisted on no simultaneous subs?
Is that something I should be insisting on considering that we don't pay pro rates yet?

Not sure how to proceed, but I do know that it's frustrating as hell to accept a story, plan out an issue, and then see the work get withdrawn--especially if I've already edited it.
I'm inclined not to accept any submission from an author who does this. But I'm not sure if that's reasonable, or a sign of petttiness on my part.
(I wasn't going to tell anyone this, but I can be damn petty at times--Ha!)

Little help?


In other news, tomorrow night is Ghost Shark.
If you're in the neighborhood and want to come by, it comes on at 9pm.
I also made chocolate chip bananna bread with pecans.
