I've gotten a lot of interest in writing for Select a Story from established authors and newbies alike, but many ask me how to go about writing an interactive story and other related questions. Moreover, I've seen some consistent issues pop up in submissions.
After writing dozens of emails in which I reiterate the same points, I've decided to write a blog that I can direct writers to which answers all of their questions.
Each post can be read individually if you're curious about a particular issue, but if you really want to get serious about writing interactive stories, I'd recommend reading the entire blog from beginning to end. (That is, from oldest post to newest.)
P.S. If you notice, below this post is the link to the next blog in the series. How helpful!
