We're proud to announce that, starting today, anyone can now sell items on Marketplace.tf! Until today, those wishing to sell items needed to apply to join the closed beta, and wait to be accepted. This is now a thing of the past: you can now become a seller in less than a minute.
To become a seller on Marketplace.tf, simply visit the sell page, read it thoroughly, and click "Become Seller". Any user with a valid email address may become a seller. For more information on the seller experience, please read this blog post.
