Delivery - Initial Foothold

I am stuck on obtaining the initial foothold. Following are the things I tried:

  1. Opened a ticket
  2. Used the information to sign in
  3. Tried posting message with embedded links
  4. File Upload - Performed basic checks but no luck
  5. Tried different combinations of username/email/name to get into two other portal but no luck.

From there on I am unable to piece together how to obtain access to M**M server. I just need a hint on the direction to move forward.
