To create an account, go here. It's pretty straight forward on what to do, and should be easy enough for everyone.
If you want to be added to the community after you've created an account, go here.
Each person who posts a story is asked to use a tag (use the story's title), when they post each new chapter. This way when you want to read a story, all you have to do is click on the story title in the tags list.
This community is set to automatically lock the posts so that only members can view them.
