You could do something like Barter with collapsible menus.  Or you could list all the games and then have tags/colors next to games you already own, games you have available for trade, etc.

We have to search for the game and do it individually for each game? That's quite a hassle. Can we have an option to include games we already own in the trade window?

I know it's not exactly the same layout but people notice it's similar to barter's. Maybe people get that feeling like it's an imitation. Like, why use a site that's like the original when the original works fine? Or maybe they're like me and don't need a third trading site to deal with.  I don't know. That's my take on it but I could be totally wrong.

I did notice LT's bundle info page was a lot better than bvg's. It has more info and is separated correctly by tiers which barter should have done.

Like I said, if barter had died I think everyone would have migrated to LT and been happy. But it didn't so now your site feels like a copy/redundant/unnecessary?

What if barter became your site?  Like transfer everything over and both of you could manage it? Traders wouldn't have to juggle another site and we'd all get to use the better layout. Would that be possible?

Actually I was planning on using LT for trading when barter's site was having login problems and we all thought the owner of barter was MIA but I gave up immediately after I couldn't figure out how to remove a game. I could add a game but didn't see any way to delete a game so I just went back to barter.

But I think the main problem is that the sites are too similar, which I know was the point. LT was supposed to replace barter so it's not a coincidence that many UI elements are similar to barter's. LT is clearly a better looking site than barters (which is pretty ugly) but functionally they're quite the same. So when the owner of barter reappeared and it was apparent that barter was not dead there didn't seem to be a reason to use LT for trading because it felt redundant. If barter had died I think LT would have successfully assimilated its userbase because it felt like barter 2.0.

Maybe you need to redesign the site so it doesn't feel like barter's anymore. Having an attractive site is nice but most users will probably prefer function over form and if they both function and feel the same then they're going to stick with the site they're used to and is more popular.

It's a waste of other's time because I don't use this site for trading and won't see their offers. There is nothing wrong with your site of course. I just don't need a third trading site to keep track of. Two is enough for me. This site and barter.vg are similar enough already.  I agree that functionally this site is far superior to steamtrades but steamtrades is popular and was the first trading site I used.I made it all uppercase so it would be more noticeable to traders.I don't see why it has to be an all or nothing approach. You're able to disable trade offers on barter and still use the site. I'd still like to use the search function on this site.  I'm just trying to be considerate to other traders and not waste their time looking at my list and making offers I won't respond to.
