How do I use ‘Connect Events’ for the ‘self-registration’ of external users for a ‘Connect Training’ suite of Courses?

It’s really not a lot different from creating a registration page around a Meeting Room.
To attach this to a specific piece of Training Material:
  1. Create your Curriculum or Course
  2. Create your Event (‘registration page’)
  3. Instead of choosing a Meeting Room, select ‘Present a Connect Pro Training Course or Curriculum’
Figure 1

After this they will have a login in the system and from their ‘Home’ tab they can select Courses from the ‘Training Catalogue’ tab if you have indeed made the Courses available there.  You can arrange them by folders to make things more structured.
To just create a ‘Registration Page’ that allows them to register and simply create a login for themselves, follow the same process as 1 and 2 above, then choose ‘Present Content from the Connect Pro Library’.  Select a PDF you have placed in the ‘Content’ section if you want them to be able to read instructions from there (or download it to their desktop for example).
You could make it so that you never actually send the final ‘click here to view the PDF’ e-mail by creating editing the e-mails that are sent to the registrant to include the instructions in the text.
The instructions for making an event (registration is the same) are in the Manual at the link below:
The right way to do this is to test it yourself with a simple example and making a login for yourself or an alias of yourself (your private e-mail for example).
