Checkout the links, contests, markets, etc. Victory Crayne is the moderator. Must critique a minimum of words before you can submit writing for critique. Submissions must be hardcore science fiction and must be part of a novel you have written or are writing. Critiquing in this group is very polite, but honest.
Participants are from all walks of life.
I have participated in this group and plan to again when my available time allows. Please read it.
