How can I get credit for answers I wrote in a sister site that were moved to superuser?

Question

I answered these questions in SO before they were migrated to SU:

http://superuser.com/questions/228878/how-can-i-concatenate-two-files-in-unix

http://superuser.com/questions/228853/how-to-find-the-largest-file-in-a-directory-closed

My accounts are (or should be) linked. Why don't I get credit for this?

Answer 1

We just deployed a better method of tracking ownership across sites; you now own these answers.
