In order to address recent bot activity, input validation has been tightened on the form elements in GO available to non-authenticated users. This includes a captcha validation challenge on the “flag as inappropriate” area for non-authenticated users. In order to avoid having to fill this in you can always authenticate with your Middlebury account via the “log in” link at the top of go.
Also some usability enhancements have been made on the administration back-end to make GO administration smoother.
