From September 1 to October 15, 2007 invitations may be submitted through wireless messages by texting “DMB” to 9-5-9. This option is only available to AT&T customers. All fans, regardless of service, may submit invitations online at attblueroom.com or by mail. Invitations may include essays, photos, videos or sound clips. Fifty invitations can be submitted by each person, each day. The promotion is open to fans aged 18 and older. The most creative invites in each category will win a flight for two and VIP tickets to the concert. Dave Matthews Band will post a sampling of invitations on its MySpace page at myspace.com/davematthewsband as well as the Warehouse and DMB websites.
