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<http://www.timeanddate.com/worldclock/city.html?n=241>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 Dbl2010
