Welcome to the site! I am glad to see someone is using the Extend-A-Story software. I did not write it, but I have enjoyed creating episodes for the Never Ending Quest with it.
I went to your site. It looks like you have done some work on it. I have not posted, as I do not want to start things off in the wrong direction. I am not sure about the concepts of restart and cascade. It may be something that your audience already knows. It appeared to me it was a way of creating extensions that was required within the limits of a previous system. The way that the Extend-A-Story works, the links are texts that describe options that the writer might take. The links are usually part of the story itself. Click on the link, and you are in the next section of the story.
Also, in reference to this comment on your index page...
However, please don ask me ta fix single typos, or grammar mistakes. Everybody makes em. An Ah'd never get ta do anything else if Ah started spell-checking tha entire Addventure.
Extend-A-Story allows a writer to correct the minor typos that you cited. The default on this site is 30 days. There are good and bad points to allowing the author to edit. An author can post something quickly and keep the momentum of the story going, but still clean it up so that it looks professional within a few days. The danger is that an author might make a minor change that would contradict what other authors post afterward.
I do have one tactical suggestion. Play through three choices from the beginning of the "Never Ending Quest" story and look at how Sir Toby (the site owner) set it up. He established the background in episode 2 (Middle Ages fantasy), with a base character (Lord Fred) that we would follow, and just two options (left or right). Then he added some simple choices that allowed the episodes to develop differently. "Do I go toward the light or follow the water?" "Do I meet a little dog or a bear?" "Do I avoid the man studying the book?" Sir Toby limited the number of choices to two for the first three levels of the branching tree, and then let other authors start creating stories after that. You might want to do the same thing and create some of the early episodes yourself, just to establish which anime universe you are in, and who are the starting central characters.
Good luck, and I hope that you can contribute to an episode or two on this site.
