A friend in my flash group just wrote to me yesterday that she received two acceptances for the same flash in the same day but had already written to the first one. Now something similar happened to me.
I did some withdrawals of "Champagne" after it was accepted at TRAMPSET. Originally I sent it somewhere after a solicitation, and when they were taking much much longer than the few days they'd promised (I still haven't heard from them, and it's been a couple of months), I sent it out to just a handful of other places. When I withdrew it from one of them, a really cool print magazine, they wrote back that they'd accepted it! Hadn't I gotten the email? I hadn't. They don't use submittable. I checked my spam and didn't see it. I had submitted via email, so I think it would have been in that email string, but it wasn't. I think it must have slipped the editor's mind. Would have been a nice publication, but I love TRAMPSET, so all is well. Maybe I'll place something in the other mag when they reopen in December.
Often in the past I've had flash to spare, but lately I haven't been writing flash at all, so just about nothing is out. I decided against revising a couple that I just wrote in Kathy Fish's class. Hope to get something from the Ojai retreat. One good flash would be enough to make me happy.
