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

anda 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 anda have it on a (safe) website then anda can put a link to it in the pautan section.

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

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