@EmmanuelMuyenza ...
We are glad you are here in the Canvas Community, but I think you may have posted to the wrong area. This is the global Canvas Community website, and it is not a part of your course that you may be taking. This website is for people to come and ask questions about Canvas ... and also a place to review "how to" written tutorials and video tutorials about Canvas. I think what you'd want to be doing is posting your above information in the class you are taking instead. Here is a video tutorial for you that might help:
Discussions Overview (Students)
The best way to find out where to post is to contact your instructor. Instructions on how to do that can be found at:
How do I get help with Canvas as a student?
Good luck to you! Let Community members know if you have any questions about this...thanks!
