No, I did not suddenly receive an influx of rejections on Project 2. I simply decided to recategorize my "no-response" queries as rejections. Some of them have been hanging out there for quite some time.
It is possible that there was a spam filter incident, and that some of those queries were whisked away to the technological never-never. And maybe, in a few months, I might re-query some of those, just to see if I could get a response this time. But for now, I'll mark them as "no"s, and move on.
I did send out three new queries today. Let the drubbing commence.
