Redirect Option removal

[neo|d3fx]

Hey coders!

I have an odd request, and it might turn out to even be a simple edit, but all searching I've tried has turned up nill.

Is there a way I can remove the option itself, to move a thread and leave a redirect? I am an admin on a large forum, and we sometimes have the issue of people doing this, by mistake at times, and it gets quite messy. We try to have them just move the thread to it's source as we have an auto-pm hack install that lets the thread creator know it's been moved and where too.

I'll add an image just to clarify, incase you are confused. I just wish it to not be an option any longer.

Thanks!
