Code/Hook help with editor box in newthread.php

[Opserty]

I don't understand why you want to make two editor boxes and then merge them together, doesn't that defeat the point of having separate editors?

I think you need to check newthread.php to see how the $messagearea variable (which contains the editor) is generated. (Possibly done using functions in includes/functions_editor.php). Then also check newthread.php and follow what happens to the input from the text area, you will just need to duplicate this and edit the POST names. What you do with it after that I'm not quite sure.
