We have a new feature available in the Steam Community Hubs: Trading Forums. You can find a trading forum in any game's Community Hub under the "Discussions" tab, making it an ideal place to look for trading cards for those games.

These forums also work with Trade Offers: If you have a publicly visible inventory, anyone reading your Trade forum topic will be able to send you a trade offer, even if they're not on your Steam friends list. Once you're done with your Trade topic, you can close the topic to prevent further trade offers from it. You can also find a list of your open trade topics from your Trade Offers page.

The rules for trade forums are a little different from general forums: posts do not get "bumped" when someone replies, and you are limited to one post per day in each trading forum.

If you've got any feedback on the new Trading forums, be sure to leave a note in the discussions area.

Hello everyone,

We've updated the Badge Showcase on the profile. When you select the Badge Showcase, you can now choose from one of four styles:

• Rarest Badges - The least common badges you have are shown. This is the default.
  
• Most Recent - The badges you've most recently unlocked are shown.
  
• Selected Badges - You can select which 6 badges to showcase
  
• Random - The showcase will show 6 badges at random, so it will be different every time someone views your profile.

As always, let us know what other customizations you'd like in the comments or in the discussions.

Hello everyone, we have a few updates today:

• New "Booster Pack Eligibility" dialog - you can find this in the top right of your badges page. It will list the games where you are currently eligible to receive a booster pack.
  
  
• CS:GO Fix - We've fixed an issue where some CS:GO owners were not getting card drops for owning the game after last Thursday's update.
  
  
• Trade Offer Web API - For developers, there's a new set of Web APIs available for working with Trade Offers. More information is available on the Valve Developer Community Wiki.

As always, be sure to leave your feedback in the group discussions area!

Today we’re shipping a new feature we’re calling Trade Offers that allows you to send a prepackaged trade to a friend. It’s similar to regular trading, except you propose the items for both sides. You select the items you’re willing to give up from your inventory and what you’d like to receive from your friend, and send it off. Your friend will receive a notification in the green drop down and can then choose to accept, decline, or make a counter offer. Unlike regular Steam Trading, you don't need to both be online at the same time. Plus, trade offers can be sent and received using a web browser.

You can create an offer from a few places: from the Trade Offers page in your Inventory, from a friend’s Inventory, and from any of your badge pages you can send a friend a trade offer based on the trading cards you still need collect.

Here are a couple of frequently asked questions:

Who can I send an offer to?
Currently you can send trade offers to your friends, though we may expand this in the future. Note that trade offers respect Inventory privacy settings, so if your friend has their inventory set to “Private” you cannot send them a trade offer.

Can I send more than one offer with the same items?
Yes, you can send more than one offer containing the same items. When an offer is accepted any other pending offers with the same items will expire.

How long is a trade offer good for?
Trade offers automatically expire after 2 weeks. You can see the offer expiration date at the bottom of a pending offer. You can cancel any pending offers from the Trade Offers page.
