I think there are still slush threads at the
Baen Bar -- I've heard enough slush horror stories to make me avoided them.
Anyone who signs up with that forum can read the slush posted there, so if anybody wants to have a look to see what sort of stuff gets slushed, there's a good place to do it.
Please note, however, that I have no idea how representative of the species the Bar slush is, if somebody who (unlike me) has actually done real slushing wants to comment on that, I'd appreciate it.
