Digital Medai Lawyer Blog:  “Online contracts typically fall into two categories: clickwrap and browsewrap agreements.  In clickwrap agreements, a user expressly indicates his/her assent to a website’s terms of use by clicking on a button that says ‘I agree’ or ‘OK.’  In browsewrap agreements, a user does not expressly indicate his/her assent by clicking on a button, but ostensibly indicates his/her assent to the site’s terms of use in some other fashion – such as by submitting information or clicking other buttons.  Courts routinely enforce clickwrap agreements.”

The case is Major v. McCallister, Missouri Court of Appeals, No. CD29871 (Dec. 23, 2009).
