Hi, TheSheriff1985, when you say 'series', how long is the series we are talking about? Three, four, five parts? Or do you plan something much longer?
Do have a look at my stories, here is the link: Wxt55uk's Stories. You will see that I have written quite a few series that range from 2 to 102 parts.
If you are looking to write a shorter series, then I would suggest planning it and then writing it in its entirety. Post a part, and do read feedback when you get it, before you publish the next part. Do be prepared to adjust the storyline if, from your feedback, you think of something new (better) - tweak the story.
With longer series (books), my first 6 were all (to a degree) planned out, and I was always several chapters ahead when a published one. One tip is to publish in the genres the chapter fits, rather than putting them all under novels. You will get more readers, as from experience I have found LushStories members seem to be put off when they see the novel tag.
My latest series, "Cash in Hand", morphed into a long series. It was never planned. I just thought of a story and hung it around the characters I had created. This is far more difficult to do. "Cash in Hand 2" will be more thought out, and I will be writing a couple of chapters ahead of what is posted.
Here is a link to the first chapter: Cash In Hand 1 - "A Job Opening?" - Part 1 Of 2
