Choose Pvp Non Pvp Char On Login

[gaffeltron]

Hi, just wondering if its possible to create a script (or if someone knows if one allready is made) that forces the char to choose to be a pvp or non pvp char. when they login the first time, a choise that can not be undone, non pvp would make them "non attackable" and block them from joining battlegrounds ...... just an idia.....
