We are not currently accepting logos. We want to keep it in-house for the foreseeable future.
At LogoGround you can sign up, upload your logos and you keep (at the time of writing) 100% of the profit when your logo sells. Each uploaded logo is individually approved before it is published on the site. The emphasis on quality means you can focus on creating brilliant logos, rather than trying to compete with designers who attempt to flood the system.
It's free to join. Check it out:
