What is the formula for Arena PvP?

[Mongoose]

Was wondering if anyone has the script to make /duel and Arena areas PvP enabled. Never seen the new Servers with it so I need to put it in manually. Any help would be appreciated.

I have the layout for it and the basic stuff done, I just need to polish it off before I upload it into CVS =)

Ok, keep us updated :D
People on my server want PvP enabled and Crits and AA, but AA script won't work for me. I'm hoping the PvP does though
