You keep putting the cart before the horse. As you can see, I have some facility with language. I'm just saying that the button is not necessary, and it's more of a management headache for moderators.
Again, no button will make me sell to a flake or someone I don't want to sell to, and it doesn't fix the flakes or scammers. Also, I want to be able to have backup buyers.
IF the button is implemented, it should be a *starting point*, and more than one buyer should be able to hit it. Then, the seller vets the buyers and sells to the most-qualified and/or most respectful, best offer, best ability to meet at a favorable FFL, best availability, etc.
E.g., some buyers are qualified but can't muster a weekday or weekend meetup which might work for the seller. Some may have a strong preference for an FFL which takes forever to do DROS anything whilst hating doing it. Some won't drive more than a couple miles out of their way, and so it goes.
Even with this idea with the button as starting point, it would be like how it's always been, especially on this site.
