Can we repost a question?

Question

If we can then how and if not why we can't do it.

Answer 1

If you couldn't, 90% of Q&A would be empty. So many common questions...

Is Sololearn certificate worth anything?

Which is best language for web? HTML or CSS?

How to hack Facebook?

What's the difference between Java and JavaScript?

Do my Computer Science homework please.

Answer 2

Chances are everything you post will be a repost anyway.

A challenge would be posting something that hasn't been already. For me it's doing a search to find an answer in the sea of reposts before I make my own.

That or present my own post so that I can collaborate with fresh/experienced minds, and to reference more conveniently. Sometimes it's how you ask/make the post that yield more (...or less) favorable results.
