ANY VISITOR can add content ONLY if they are MEMBERS "logged in" or a VISITOR who has REGISTERED their email address with National TU. 

If you are a visitor click this link http://www.tu.org/user/register .  In order to register you will enter your email address, create a password and hit submit.

This process is necessary to make sure that a user is not some type of malicious "robo" email. This protects both the user & TU.
