When I enter details on the registration form Continue button is not got enabled until I select I agree to receive other communications from Topcoder. But it looks like not required. And after I unselect it the Continue button stays enabled.

@RishiRajSahu could please clarify which behaviour is prefered here? Is selectin I agree to receive other communications from Topcoder. required? Or should be Continue button be enabled even without selecting this checkbox?
