Hi :) i got your msg but my instant messenger isn't letting me type stuff so i'll write it here...
of course i can help :)
ok, go to the upload button at the right hand top of the page :) click on it and you should be directed to a page which shows your stories.
(make sure your first chapter is there already)
click on the "creat story group button" and fill out all the necessary info on the pop-up that appears :)
then at the bottom of it, there should be two boxeslabeled "not in this group" and "in this group"
in-between there should be arrows pointing from one box to the other. click on the stories you want in the one group and upload it into the "in this group"box....
from then on, whenever you want to add a new chapter, go to that upload button again and you should now see your new story group. if you hover over the title, to the right a bit, there should be a "+" sign. click on that and you should be able to add a chapter :)
i hope this made sense :s
