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

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

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

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