Because some peeps appear to be looking at this...newcomers, gaze upon the articles below!
Those mostly apply if you want to have your story 'published' on the site, which is great as you can get strangers feedback!
HOWEVER, the most IMPORTANT article for you all, which I strongly advise checking out, is this one:
There are rules for dialogue punctuation, but from what I gather, they are not really taught. Further, at least one story published by this cohort had incorrect dialogue punctuation. As such, if any of you care for writing (which you probably do, considering the course name), I'd advise trying to ensure you understand this properly. Heck, even if you don't care I'd still advise learning it.
Your teacher/tutor/etc could probably teach this, but I obviously know nothing about them and the course goals, but I'm pretty sure if you want good storytelling (through writing) you want correct punctuation (or at least to have mistakes be intentional).
Regardless, if I can spread this knowledge to multiple people with one post, I'd be pretty happy.
P.S. Here is an external site that has a good deal of examples: Editor's Blog: Punctuation in Dialogue
