Single post in Adding a message to completed trades!

I would absolutely love this! From someone who is always nervous to send thank you messages in fear of annying people who don't want to be PM'd. This would be especially useful for gifts! Since the only option for the giftee to communicate to the gifter is a direct PM, it'd just be nice to send a small thanks via the gift acceptance itself! (And also as someone who does a lot of trades, I always feel bad when I send a trade and the person says thank you to me, but I can't say thank you back to them when I confirm the trade.....It's not important enough for a separate PM but I'd still want to say thanks back just to be nice. ;-; )
