Good advice here already. The easy way is to just copy and past the links to your latest installment. Mark them with what order they are in. If you want to be a bit fancier, you can use HTML to embed the link in the description. So the link to the first installment would be highlighted blue, but read "my story part 1".

The code is simple, but if I type it, it will create the link. If you are interested in going the fancy route, let me know and I will split the HTML up for you to make it easier
