Looks good to me, for other reviewers, that enum is defined here:

Dnn.Platform/DNN Platform/Library/Common/Globals.cs

Lines 341 to 362 in 9f83285

	public enum PortalRegistrationType
	{
	/// <summary>
	/// Disabled Registration
	/// </summary>
	NoRegistration = 0,
	/// <summary>
	/// Account need be approved by portal's administrator.
	/// </summary>
	PrivateRegistration = 1,
	/// <summary>
	/// Account will be available after post registration data successful.
	/// </summary>
	PublicRegistration = 2,
	/// <summary>
	/// Account will be available by verify code.
	/// </summary>
	VerifiedRegistration = 3,
	}

Thanks @david-poindexter

@valadas thanks for linking that. Honestly, that's what took me so long - finding that enum! 😆
