In reference to what you two say, then maybe not post the plaque/tablet. But still, they should somehow be told the basic rules, which is hardly the entire battle philosophy.

A couple examples of things rager apps need to know, but can't read/help are things like they are not susposed to attack non mage/enemycabal players... and you can't kill a guy who eats a dried yellow flower or is wearing a charred bracer.

The battle applicant process is AUTOMATED, as such, they should be able to find out the rules without player interaction as well.
If not make a helpfile, maybe make Tahren say the rules when you become an app, such as the ones outlined above.

Since its automated process and imho its unfair to only give them "non-automated" access to the rules. Unfair like in, the newbie killed four guys for wearing charred bracers over the course of two days because he honest to god thought (Theyre using magic) it was ok... and by the time a battle player finally sees this, he gets kicked.
What about the 3 am battle app newbie when membership is low?
