Beyond comments, another good way to provide feedback is through flags. There hasn't been widespread flagging this term so far. Since it is a common way to communicate and control content in online settings, I suggest you do more of this with as you read others work in the class these final weeks. 

Flagging is a notation or mark associated with content. There are several flag options on posts, which you will find linked at the bottom of each post. Simply click the appropriate flag and the work has been flagged. You can toggle the flag on or off by clicking the link.

• Inaccurate/Inappropriate: This is a flag that can be used for an posts containing problems. This allows for typing of a comment along with the flag to better explain the issue.
• Nominate as Outstanding: Click this if the work extra impressive.
• Needs Citation: Information that lacks references to support the information or includes incomplete or inaccurate citation information according to APA format.

Flagging definitely contributes to your grade but more importantly, it provides feedback to others and ensures credibility in content. In essence it is a peer-review system of ensuring information is acceptable.
