Is a user allowed to post the same question on multiple Stack exchange sites?

For example, what if a user posted the same question on both Superuser and Stackoverflow?

Or, should the user just wait for answers on one site?

    That's called "cross-posting".

  • @AlEverett It is, and that's the term I use, but "multi-post" is also an acceptable term and arguably a better one, since cross-posting has another meaning too. Commented Feb 16, 2013 at 21:18
  • That's as may be, but around here "cross post" is the common term, and if one wants to find out information already established here, one will find more information under "cross-post" than "multi-post".

Cross posting is frowned on.

It makes migrations really difficult.

If you have a question that can fit on a couple of sites, decide which on it is more suitable on and ask there. If, and only if you are not getting any answers within a few days, consider asking again on the other relevant site, linking to the original and explaining you didn't get any answers there.

    I'd also add that you should tailor the question to the site's audience as well. It's rarely true that exactly the same question is on topic on multiple sites, but questions on the same topic but asked from different perspectives with different emphasis might be,

If you post it on one site, it is probably off topic on the other site. Do not post your question on multiple sites; read the FAQ page of the sites and decide which site would be best to ask on.

If you're really not sure, you can ask on meta with the tag .
