Bb Open LMS/ Moodle

Good evening,

I am enrolled in EDTECH 501 and I can't do many things in the course (post in a certain forum, not showing up as a participant, etc). When I click on Participants, it says:

Sorry, but you need to be part of a group to see this activity.

Can someone help? I know my professor asked other students to help me. Am I enrolled correctly?
