I have a feeling I'm not the only one whose thought cs could use some updates. Here are some of my ideas
1. allow people to make offers, including gold and items. Allow them to attach a note also.
2. get an ingame notification if something sells, OR you get an offer on something
3. when an item sells, return some of the auction fee. I think one of the uses of the auction fees is to keep people from spamming cs with torches for 999m(you get my point) and I think it really isn't a game changer, but it doesn't hurt.

post your ideas below!
