Hello, there is a confusing line at this page:
http://wikimania2007.wikimedia.org/wiki/Cancellation_Policy
Section : If you pre-registered with accomodation
"Cancellations filed before Sunday 20th May 2007
Taipei, UTC+8 will be taken into account and partially refunded. However, if you submit it later than 20th July, 2007
, there will be no refund."
Is it 20 May or 20 July?
Thanks
