ANGELA HERE. Sorry to bust in at the top here.
I did receive your entries and I did send out confirmations to everyone. I have no idea what is going on with spam filters but I spent hours yesterday sending out confirmations, often 2 or 3 to the same person. Some were getting my emails but others apparently were not.
I did respond to every single email. :)
I was wondering about that, myself, JDP.
I was a first-time entrant in the summer contest. Like you, I sent my story in on time...not four hours early, but 30 minutes early, and I haven't received confirmation of its arrival, either.
Just to check that my email provider wasn't holding messages, I sent the story to myself at a different address, different email provider, at three minutes until the deadline. It got to my other email address on time!
I didn't know what to expect regarding confirmation, since they have several hundred stories to confirm, but your experience is very troubling. I was giving them the benefit of the doubt, but now I'm concerned.
Please spay/neuter your companion animals. And when it's time to add to your four-legged family, save a life by adopting a stray or from a shelter or rescue group.
