From Khoi Vinh: Somehow I ended up creating multiple user accounts (under sepa­rate email addresses) over at TripIt (which is prob­ably my favorite travel tool of the past decade). For a recent trip, I had stashed some data in one account and other bits in another. But thank­fully TripIt made it rela­tively easy to consol­i­date these accounts together; after some simple email veri­fi­ca­tion, I had a single user account that recog­nized both email addresses. · Go to Multiple user account disorder →
