Your best bet would be to add a player.pl file to your starter zones or use the new global player.pl file.  You would just use the enter zone sub event and check if they are level 1 (or anything less than 50) and then set them to level 50 using a quest command.  It would be something like this:
	Code:
	sub EVENT_ENTERZONE {
	if ($ulevel < 50)
	{
		quest::level(50);
	}
}
 There is no real DB setting for doing what you are wanting.
