Speaking of Baen's Bar as I did in my last post: I was on a panel at Fencon with Paula Goodlett, the assistant editor of Baen's Universe. I was on two panels with William Ledbetter, who's been published by Baen. Both soundly espoused the efficacy of Baen's Bar as a place to post stories and get feedback.
Baen's Bar is secure and you have to get a password and all, so from what I hear posting a story there is not considered publication. Apparently it has a high level of quality among its participants.
I need to check it out as place to post stories that need critique and feedback.
