Is php v5.4 really necessary?

Yes, if you expect me to write neat, maintainable, legible code.

Find the post in the post overview and use the row action "find orphans". You will then be presented with a table of possible orphans on each blog. Select the blog and then choose "link orphans" to create the links.

To be considered an orphan the orphaned posts must have the exact same title (name) as the soon-to-be parent.
