Question: How do I "join" groups in Customer Connect?

Content

Hello Learn Group! 

I would like to join the "Learn Members Group" on customer connect. I spent time reviewing the site and can not find a way to "join". Is anyone able too provide me with instruction on how to become a member of the relevant Learn groups. Also are there any other groups aside from the main one I should join? 

I had my account manager assist me in trying to find how to "join" and we are both stumped. 

Thank you for your help with this matter!
