I had P411 back when I first started out in the hobby (2012). Eventually saw enough ladies that would serve as references that it didn't seem like it was necessary.
Now, with the upcoming changes, strongly considering reigniting my P411 membership. Figure it's safer in terms of screening, finding legitimate providers.
My main questions are: 1) are there providers out there that take P411 as their sole screening mechanism and 2) are there enough providers on P411 to make it worth it?
