The contributors list should include the joining date of each individual, displayed directly below their USERNAME.

Why is this important?
1️⃣ Tracks Consistency – Helps in assessing how long a user has been contributing, making it easier to identify consistent contributors.
2️⃣ Adds a Differentiating Factor – Highlights the seniority of contributors, distinguishing newer members from long-time contributors.
3️⃣ Enhances Transparency – Provides better insights into engagement and commitment levels within the project.

This small yet impactful addition can improve contributor recognition and motivation! 🚀
