I still want to be able to filter out or exclude certain phrases and/or sellers when I look at ads.
A feedback system would be nice. Unlike eBay allow sellers to leave negative feedback for deadbeat buyers.
GunBroker has a function to allow sellers to block specific bidders/buyers, which is an awesome feature when you get solicited by a user to sell off the books/without paperwork... uh, no, either you're a felon or you're ATF so go away... and I've noticed that there are a lot more criminals and scammers in the herp world than the gun world.
