Mags, I had done it the way I was instructed (putting the statement under a heading "DNA Confirmation" as the very last thing on the profile) until I saw an example Peter Roberts posted in answer to a recent question about how to do it. I *LOVE* what he does - when he mentions the person's name in the bio, he adds a footnote, using the DNA confirmation statement as the citation.
EDITED TO ADD:
I just looked quickly, but can't find the question I referenced. I did use that idea on a profile, though - you can see it on THIS ONE.
