Can someone shed light on the preferred arrival date for Wikimania? The Programme page has dates listed from June 21 to June 28, but 21st, 27th, and 28th are left blank.
Also, Wikimania Takes Lake Como (WTLC) is planned four days prior to 23rd (20th-23rd?). Does that mean folks who would like to attend this, needs to arrive on the 19th?
