Copy and Paste Allowance

1) Copy and Pasting is not allowed in projects to make it harder for people to cheat and plagiarise other people's code instead of doing the project themselves. However, there is a little known secret that you can use inspect element to select the code editor element and then remove it's on paste event listener which is what is preventing you from pasting code.

2) That would be a very cool feature, but it likely won't ever be implemented because it would be a complex thing to make and maintain. Having multiple people edit the same code would be hard to make in itself, but then they have to make sure the connections aren't leaking people's IP addresses. And they have to have servers constantly doing all the connections. Real time connections like this would definitely be misused and nearly impossible to moderate.

2) That would be a really cool feature, and I totally support it, however the chances aren't likely.
