It is in the changelog.txt from almost a year ago:

Rules Values Character:MaxLevel needs to be set higher than whatever max level you use for this because this is per character.

Example:
templates/global_player.pl

sub EVENT_CONNECT{
	### If the Character doesn't have a max level defined, let's define it (Level 70)
	if(!$qglobals{"CharMaxLevel"}){ $client->SetGlobal("CharMaxLevel", "70", 5, 'F'); }
}

Let me know if you have questions.

Edit: You need to have rule 'Character:PerCharacterQglobalMaxLevel' set to true
