[2) Promote yourself! If you're just posting your stories in the eFiction section of the site here, you're really limiting yourself. Start posting your stuff at Nifty. You'll reach a much wider audience there, and will get even more feedback. Once you start getting a "fanbase," you can also start up a Yahoo! group, or maybe even your own small page at Geocities or somewhere (all of these things are free and easy to do). When you submit new chapters to Nifty, link back to the eFiction section and encourage your readers to come to GA and discuss your story in the Story Cafe forum.
I have considered Nifty, as I have been reading stories on that site for years. I have not posted on Nifty frankly because so many of the stories I have read on that site are so sloppy - poor grammar, worse spellling, and just plain carelessness seems to be the order of the day at Nifty. There are, of course, many exceptions to that rule. After much soul-searching, I chose to present my efforts among more illustrious company, ie RCWP and this site.
