Heather Reasonover opted to try Internet service from Clearwire Corp. Clearwire sent her a confirmation e- mail that included a link to its Web site. Clearwire also sent her a modem. In the enclosed written materials, at the bottom of a page, in small type was the Web site URL. When Reasonover plugged in the modem, an “I accept terms” box appeared. Without clicking on the box, Reasonover quit the page. A clause in Clearwire’s “Terms of Service,” accessible only through its Web site, required its subscribers to submit any dispute to arbitration. Is Reasonover bound to this clause? Why or why not?
