1. You can write on the forums just like you just did
If you mean stories, you will see a writing forum on there if you scroll down. Just post in the appropriate forum. We also have blogs now too.
2. The site will possibly shut down because the expiration date is next year. With the lack of updates(fully explained in the Forum Feedback thread), chances are it will close. If not, its lifespan isn't going to be much longer to begin with. Tops, 1-2 years of renewal, which may seem like a lot, but with time on here, you find it runs out quickly.
3. Just click the provided link
Once there, you can choose to register if you wish and explore our many new options. I'm currently adjusting the layout colors, so forgive the strange look it has right now.
