Thank you for replying.
There is another question, now that I've started submitting. How many episodes at a time is appropriate?
I tend to write first, then divide into episodes, then submit. This means a lot of potential branching points, but it also means I may end up submitting a lot of separate episodes at one time. Right now, I've got a lot of episodes lined up to be cut/pasted, but I don't want to spam the list.
