I found out meanwhile lol'ing around on my server that if you change the "RACE" in mySQL Datebase on character.
From exemple 1 to 6, You get the right faction, but not right racials etc.
After thats done do a character customized, You get to select right face and such, and soon as completed, voolah.. you got right racials rep & evrything
If anyone can code this so it REQ char name & select what race etc. & gives the customized, i would love to see it
Note im running on MANGOS
