Editing Stories problem

[Sonic Purity]

Greetings,

Just uploaded a new novelette today to Your Stories (Quality Without Compromise®). The only way i know how to upload stories is to make the first chapter the original post, then reply to myself for each additional chapter. I see the Edit button for the original post, but not the later ones. I found a couple of small errors i’d like to fix, but without an Edit button for Ch. 3 and Ch. 8, i don’t see a way to do this.

Is there a way? If so, how?

Or is this like Dimensions, where after a few minutes everything locks up forever?

~ Thank you! ~
