The Steam Winter Sale is going on, which also means it's time to vote for your favorite games in different categories. While doing so, I noticed I had two gifts in my inventory, so I suggest you take a look at yours. In the main Steam window, you can go to your user name (mine is GregoPeck for instance) and click on "inventory." If "gifts" isn't listed, click the drop down menu button and check for that section. Keep the gifts or send them to your friends. Happy gifting (or collecting)!!

*Edit* I just tried to look for this using the instructions I gave you and now I find it difficult to find the gifts section, whereas before it was quite easy for some reason (maybe because I had gifts to send and I've now sent them).
