We used to have a quote button.
People abused it badly.
People would literally quote an entire 400 or 500 word message to add a three word response.
And someone would quote mess to add a response to it, and someone would quote the growing mess, and so forth and so on.
I named it Quotarding.
So, because people refused to think about what they were quoting, they essentially ruined it for everyone.
It would be nice if the forum software had a setting that would strip out nestled quotes (Simple Machines forum software has that), but it doesn't, so a quote button won't be coming back any time soon.
