[P1A User Story] post karma

[lynzhlang]

Description: As a student, I want to have a post karma system that accumulates the number of hearts/likes I receive across the forum so that I can gauge my contributions' impact and credibility within the community.

Priority: Low(10/10)

Justification: While a post karma system can enhance engagement by providing visible recognition for contributions, it is not essential to the core functionality of the forum. It primarily serves as a motivational tool rather than a necessity for facilitating academic discussions. Additionally, the implementation is relatively low in complexity, requiring simple aggregation of reactions across posts. However, since it does not directly impact learning outcomes or the primary goal of the platform, it remains a lower priority feature.
