Name of the website that let's you copy/paste your Steam Wishlist as links?

It's been quite a while since I've traded and I still have tons of games that I never got around to trading. However, I also want an easy way to copy/paste my wishlist as well as link each game I'm trading. I know this was very easy with a popular website where you sign in using your Steam account and can organize your trade/wishlist from there. Added onto that, it was its own sort of trading site I believe. People could make trade offers and accept trades through it.

The problem is that I forgot the name and after an hour of looking, I can't seem to find it. I believe it had "list" in it. Like Steamlist, or something of that nature. I tried SteamDB, but logging in isn't working and it doesn't look like the right site.
