":Hey, very nice instructions.  I feel much more clear about what it takes to merge and move pages.  However, when you merge, you lose the edit history of the child page information in the parent page when you copy and paste, but it still remains in the child redirect page, right?  (Perhaps explaining that this is where the child page's edit history is preserved would be a good idea because I think a lot of hesitation on merging comes from not knowing where the edit history is preserved.)   

 :Also, shouldn't you leave a note in both page's talk that you've merged the content into a larger article, so that if the child redirect is RfD'd, that history can be merged manually somehow, and people looking for the source of the new data in the merged page can see and verify where it came from?
