Poem

🐇 I stitched a market from curious hops,
I trade a trick for a clever crop,
We meet, we teach, we laugh, we play,
Skills bloom bright in the light of day,
A rabbit's note: learn, swap, and hop away!

1-34: Comprehensive project idea; URL formatting already fixed.

The project description is well-structured and covers the core requirements: user stories align with the Tier 2 scope, bonus features are clearly optional and extensible, and links are curated and properly formatted. The skill-swap marketplace concept offers good pedagogical value for intermediate learners—it touches CRUD, authentication, filtering, optional real-time messaging, and maps without being overwhelming.

The bare-URL issue from the previous review has been resolved; links are now properly wrapped in Markdown syntax.
