Download: TermsAndConditions_01.00.00_Install.zip (this link contains the install and source) (note: If using DotNetNuke 4, You must download, install, place on a page in your DotNetNuke website, and run LinqPrep first. You can obtain it here: http://www.adefwebserver.com/DotNetNukeHELP/Misc/LinqPrep/ )

The Module

After installing the module...

Under Page Settings, uncheck Display Container? and Allow Print?

Under Advanced Settings, select Display Module On All Pages

Click the Update button at the bottom of the Settings page.

When a non-Administrator logs onto the site they will be presented with the Terms and Conditions. If they Decline they will be logged out.

When logged in as an Administrator, you can select Administration.

        {
            // Only show Terms and Conditions if 
            // user is NOT an Administrator
            // user has not already agreed
            // user is logged in
            if (UserId > -1 && 
                !(((UserInfo.IsInRole("Administrators") || UserInfo.IsSuperUser))))
