okay, easy version.
Go to your Warrock Folder and look for:
"PlayerSpawnTemplate.dat"
now make sure you back it up [use WinRar or somthing]
okay now search for:
"PlayerSpawn.Name New_Player_Spawn7" (NIU coordinates)
"PlayerSpawn.Name New_Player_Spawn11" (Derbaran coordinates).
Change the 7 and 11 around.
