Darrell Schweitzer (editor, writer, used book hawker, expert) has been running a workshop for the convention for many years. He gets up to six authors to critique manuscripts, either a short story or an opening chapter from a novel. I've critiqued for him twice and I hope to critique for him again this year. I enjoy doing it. This is a fairly low-key workshop where the pros do all the work. It's usually held on Saturday afternoon and it's open to anyone, including friends and family.
It's submit-in-advance, so get those submissions ready! Then when you arrive, you have a chance to read the other submissions before the workshop starts. The usual count is three to five manuscripts. Each one gets a good chunk of time.
This is a good place to get some basic feedback from people who have been there and seen it all, writers with many years of experience. It's not always easy to listen to, but you'll get a nice range of comments.
So what are you waiting for? Put on your flame-retardant outfit and join us. http://2011.philcon.org/index.php?option=com_content&view=article&id=15&Itemid=9
PS: Even if you're not going to be there, pass the word along.
