There really isn't any policy on this. Just note that content is licensed under cc-by-sa, but Stack Exchange additionally requires you to:
(…) attribute the work in the manner specified by the author or licensor (…)
So if you quote (or copy without using visual indication of a quote) content from a Stack Exchange site, you should at the very least ...
User Contributions to Stack Exchange are licensed under cc-wiki with attribution required so there's nothing wrong in copying, assuming the attribution is given
To be clear, attribution required means:

Now that you mention it, I was somewhat curious. I ran the following simple query on both Super User and Stack Overflow to see how many users had edit permission (>= 2000 reputation):
Users.Reputation >= 2000
Which returns 488 for Super User, and 18890 for Stack Overflow. As a percentage of total users (i....
It might be better suited there, but it was asked here.
Unless a question is specifically off topic here then there is no reason to push it around the network and potentially alienate users by forcing them to work out where they end up, logging into a new site and so on.
If the user were to flag their question themselves then it would probably be ...
Fun fact: when I first wanted to ask a programming question on Stack Exchange, I signed up for Programmers, assuming that was the right place. I posted my question (10k+ on programmers only), and then figured out it wasn't the right place. 6 minutes later, I reposted my question on Stack Overflow and deleted it from Programmer's.
Fast forward a year. I ...

The choice, as to which SE site to post your question to, is an important one, as cross-posting is strongly discouraged.
The mechanism that comes closest to your question is migration, but that is likely not what you are looking for.
You could also advertise your post via Facebook, Twitter, or Google+ via the share link below your question.

It's built on OSQA, which is a well-known clone of Stack Exchange.
Stack Exchange is an original.
Stack Exchange clones
Are there better Stack Exchange alternatives/clones than OSQA?
Is Stack Exchange / Stack Overflow available for private or internal use?
We're doing the same for osx, so, why not?
Tag Wiki Excerpt
When talking only about the excerpt, then I wouldn't recommend doing this. The excerpt has enough space to explain what security is about. The space shouldn't be sacrificed for giving users directions on where else they might ask their question.
You brought up the point that a user ...
The "sign up page" that you show is accessed by clicking, naturally,
on "sign up":
"Sign up" means "create a brand new account".
If you already have a Stack Exchange (OpenID) account,
you don't want to do that; you just want to "log in":
Since some discussion about "on-topicness overlap" around Portuguese StackOverflow (SOpt) and Portuguese Super User (SUpt) arised, I decided to take the 40 example questions from the definition phase of SUpt on area 51 and analyse their on-topicness on SOpt:
Lets start with those 24 questions:

Superuser's one of the 'original' StackExchange sites, AKA the trilogy - we predate the foo.stackexchange.com sites, which I believe started with SE 2.0
So yeah, we're older and as such have a cool domain name.
Oh well... this seems to be stupid(and it is). It is related with the new questions that keep appearing when the page is not refreshed.
"One question with new activity"
The badge notification, only was loaded when the page was refreshed, and that explains why did it not appear (That minute was spent reading question titles before refreshing).
How can I set it to my network profile without having to type everything manually?
Go to your SO profile (or any profile you want to propagate to SU)
Click "Edit Profile and Settings"
Scroll to the bottom and click "Save and Copy Changes to all Stack Exchange communities"
