So we've all had that moment. When someone offers on a trade, and you take more than say...10 minutes to go double check the price. Or you're AFK when you get the offer and they've offered and removed their offer in whatever time frame that you were away from your device. Most of the time, it's an offer you would've accepted.
What if we had a timer--maybe 10 minutes or so to be on the extremely short side--where you can't withdraw your offer to allow for the poster being AFK and not being able to check the trading post in .5 seconds?
