um, i wrote a harry potter rap. is there somewhere on here i can post it?

toi can make it into a Youtube video then emble the exact thing in the box (ex.link) (the last number is fake so don't click on this) or...
If toi have it on a (safe) website then toi can put a link to it in the liens section.

(Interesting, clicking on the link brings toi to réponses that need help as well as answered questions..., cool)

toi can always post it as an article. That's what I would do.
