It's worth mentioning that on a real wiki, you want to do as little copying as
possible.
If a piece of information is found on Page X, and you copy it to Page Y, then pages X and
Y are now dependent on each other. If you change one, you have to remember to update the
other or else it goes out of date.
In real life, on a wiki you want to maintain properly, you would use a different approach.
Here are several:
* Link from page Y to page X
* Pull the information from page X into page Y automatically, using transclusion
* Make a template and transclude into both pages X and Y
Copying should be your last resort. It is the death of good information resources.
