I'd like to make all the cards in my inventory tradeable. but I have thousands of cards. Edittign each and clicking the tradelist checkbox is waaaaaay too much work. Is there a way I can just "add all" of my cards as tradeable? If noit, there should be! :D

There is not a way to do that other than manually. For newer members to the site, be aware that you can add items to your tradelist and they will be automatically added to your inventory at the same time. It's the easiest way to fill both.

W4ell, it would sure be nice if there was a way to bulk add them through the "Card Actions". There's my suggestion for the day :P
