Wow!
This is really interesting. I tried to copy and paste a conversation with Bing and post it here. I wasn't able to and wondered how Microsoft can control it. I thought it may have been a glitch in this website or my computer but I just got a response from Bing. To paraphrase: "To save our conversation you may copy and paste it but it's for your personal use, do not share it".
How did they do this?
