I'm unsure of how I want to do this... I plan on uploading by chapter but how do I keep them all together? Or is there a better option?
What I do is have one running thread for each multi-chapter thing I post, my best example being this. It has 26 replies, each of which is a separate chapter posted by me a week apart, and it sounds like it might work for what you're trying to do. There's an automatic function on LV that if you post two times in a row in one thread within one day of each other, it automatically merges your two posts (to prevent spamming), so you just have to make sure to pace yourself by at least a day (or by one comment from someone else in-between) if you want to separate your chapters. Beyond that, all I can say is don't use the blog option for literature. I for one think it would work great for some kinds of fanfic-ing, blogs here are meant only as blogs (just trying to save you the embarrassment of finding out the hard way like I did!)
Usually, we have a rule against double posting, but for certain sections (such as the Fanfiction section), we've made an exception. The easiest, and most recommended way to upload your story on Lake Valor is to make a thread, and put a new chapter in a new post. That way it'll be easy to navigate! If you have any other questions, you can always send me a PM
Small reminder - You'll have to wait at least 24 hours between posting new chapters, or else your newest chapter will automatically merge with the previous one.
