leaving a ticket for a friend?

I ordered a ticket for the Supergrass show next week, and I just found out that I can't go to the show I had the ticket waiting at Will Call and I know one of my friends who wants my ticket…how do I go about transferring the ticket from my name to hers? If someone could let me know what I should do, I'd greatly appreciate it! thanks <P>Travis
