Hi Saguaros,
Thank you for checking this out.
We've created an example menu item "Reg" in the main menu, please see the last menu item in the above link.
Also, please note that this link should take you to mysite.com/reg, but the link in fact points to /index.php/reg/team/studentregistration/ and ends up taking the user to index.php/checkout/login/
Thank you.
Best,
Roger.
