Skills Exchange

Time for time.
Skill for skill.

Marketplace terms. The Marketplace is a peer-to-peer space between members — TRAPEZIUM does not own, sell, inspect or warrant any item, skill or service listed. All transactions are between members. Star ratings are member-submitted, not verified by the cooperative. Posting and messaging require active membership and acceptance of our community code of conduct.

Marketplace

Keep value inside the cooperative.

Every swap, lend, sale and recommendation is a little less leakage out of the community — and a little more trust held inside it.
