I really like the idea that someone put up of having a warning/disclaimer, something you need to read and agree to before you can enter and post in the 911 forum.
I am unsure of software capabilities, so if it is not viable on this forum software then I guess the solution lies elsewhere. But another forum, which is vBulletin also, I am on has a certain area which you need to agree to the terms and conditions of that certain area before you enter and it is applicable every single time. Is this something the admin have looked into or are able to see if it is something that can be applied? As I said, I am not admin on vBulletin software so I don't know if it is an option or a "hack" to get it done.
