Multiquote ~ I just figured this out.
Example you want to quote (hypothetical scenario) 3 different posts in one post without having to copy and paste.
You click this button
for each post that you want to quote.
When you click the button to multi quote, it looks like this
And then when you hit post reply, you should see each of the posts that you selected show up and then you can type in between each person's post.
