Is it just me or do the links to the next chapter at the bottom of the story suddenly point to the previous chapter for everyone else too? I swear it used to work in the past, but today I checked, and chapter 4 links to chapter 3, and 3 to 2, and so on.
I do it that way on purpose for those who haven't read the previous chapters or would like to refresh their memory.
Linking to the next chapter would only work when they're all up.
Maybe people would be able to go back and edit it that way. But then you got the reverification process and extra work for the mods no one wants.
The 'Chapter Link' drop down can only point to stories you have already published. If you are submitting part 3 for example, it can't yet point to part 4.
Once part 4 is up, you can edit part 3, change the drop down link and save it. I don't believe this requires any work on behalf of the moderating team, it should just update without needing to be re-approved.
Hope this helps.
