I've just received a PM from a genius of an author letting me know that there is a way to edit stories with the current settings.
If you click on the actual story in Mange stories the little Edit button still works.
Just thought that would help!
EDIT: I'd like to remind everyone that editing fics that are in Queue will change their time-stamp so it'll look like you just submitted. This means that to us mods it will look like a fic that has been submitted after the deadline and we will delete it. So, as usual, don't edit anything that's already in the Queue while it's closed.
