There is now a place for LDS writers to gather to discuss LDS writing and to exchange manuscripts for feedback.Orson Scott Card has been kind enough to give us space on his Nauvoo website.
If you are interested in participating in this, or you just want to take a look, the introductory page is at
http://www.nauvoo.com/writers.html
and the workshop is at
http://www.nauvoo.com/ubb2/cgi/ultimatebb.cgi
You will notice that it is set up in a way similar to Hatrack, though there are differences in the software. I'm hoping it will serve a need that has existed for quite a while.
