 ## Substantive changes
 If you have specific and substantive criticisms of the curriculum, i.e. problems related to the progression/content of courses it would be appropriate to [open an issue](https://help.github.com/articles/creating-an-issue/). While it is acceptable to point out problems, all successful changes naturally require a plan for fixing the problem.
 OSSU’s curricular guidelines are [here](https://github.com/ossu/computer-science/blob/master/extras/curriculum_guidelines.md). Successful critiques of the curriculum will point out ways that OSSU is failing to uphold these guidelines. Examples are:
-OSSU lists a course as required when the course topics are elective in the curricular guide.
-OSSU does not having a course to cover required topics from the curricular guide.
-OSSU lists multiple courses that cover the same topics when fewer courses could suffice.
-OSSU recommends a course to teach a topic, but there exists a higher quality course that covers the same material.

+## Other ways to contribute
+### Responding to Issues
 Issues require more than just users to suggest them. Issues require active community members to read and respond to proposals. Even adding simple [emoji reactions](https://github.blog/2016-03-10-add-reactions-to-pull-requests-issues-and-comments/) can help the community.
+### Engaging with other students
+Learning is enhanced by engaged peers. You can be that peer for someone new to OSSU. When you see a new person posting in Gitter, ask them a question about themselves. When you see a cohort starting at _almost_ the right time, join in. Doing so will make OSSU a stronger program for everyone, including you.
