I don't think this thread should be locked.
I think it is a reasonable healthy debate to have.
By YF standards I actually think it has been pretty reasonable and constructive. I think people are thinking about the issue.
If you are concerned about the thread's original intnet LG, get the mods to change the thread title to "YF zone acceptable conduct and practices" or something.
If we just lock the thread and don't talk about it, people will continue with their entrenched views, and things like this will inevitbaly crop up again.
Better to discuss it and try and work out some common gorund.
