I almost fell into this trap too! Collections is a completely separate feature from Publications. BUT you can use the featured, trending, etc. sections in Publications to post things in any order you want, so that sort of gets around the serialisation problem that comes with the blog format and reverse chronology. Your readers can go to a landing page where your novel’s chapters are posted in order, but they still can’t navigate between them unless you’ve added links manually. In addition, only certain publications have permission to add monetised content. In Collections, there is a TOC with links out to all the chapters on the left-hand side and links out to the following chapters at the end of each chapter. It’s a really great feature that does things Publications can’t.
