Here is some other feedback: I think Agora is a great name even if I agree with @BlokchainB  that most people will be confused about what it means.

But when they get it (which shouldn't take long), it's a name that sticks. And that's what matters more imo.

I voted for marketplace. I think this is easy for people  to see buying and selling takes place here. Maybe after saturation you can rebrand the territory

Thanks for your feedback. I know isn't immediate for a lot of people. It is for now just an idea, a test... and see what come out of it. btw, what will be your preferred alternative?

AGORA

What's your preferred name for this NEW territory?

Agora is terrible name. Unless you tying to change the culture around selling things like eBay did. But most people will be confused about what Agora even means
