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

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

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

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