I agree, post your stories as a serial in stages. If its too big … it will make it difficult for members to fine time to read. And you may loose some of your audience. Also some none native English speakers read little and often. A really large post may make the effort to translate too overwhelming.
Some authors like to lock the story topic but create an OT about the topic to discuss and obtain readers views. Others like the comments between their story posts … something else for you to consider.
I'm glad Forum inspires you to write…. it did me too I look forward to your stories, and please … post as many as you wish. You will have an appreciative audience here
