Interesting stuff...is there any way to expand the thread to view all the messages? This entry, if accurate, provides a date-stamp:
7. Signed contract, without advising MCO, for "an Amazing" opportunity in direct violation of her Miss California contract 6 weeks before the pageant.
According to this
site, the final night when DK passed the title (I'm presuming that's the reference) was 01 July 2006, which puts her "amazing" contract sometime at mid-May.
