I use Date-Check, which is similar to P411. And I'm glad I did.
It was the only way I was able to see someone while I was traveling to Florida (and that tuned out to be one of my best encounters ever). Since then, it has come in handy even when seeing ECCIE ladies. If they are on Date-Check, I give them my ID, and I never get another question concerning screening. It's done and done at that point.
And once you get a few girls giving you a thumbs up on Date-Check (P411 has the same system), future dates are a cinch.
