Well when they ask that opens the door to us to explain what they have done and provide them with a petition and sign it. They must have enough curiosity to make the step of there on free will and accord.
The point Mark was making was that they come to this (or another) forum and ask how to join and members of the forum tell them "2B1ask1," instead of telling them they need to speak to a real life Brother.
I agree with Mark on another level, as well. Those stickers really don't tell the average person how it works. Most people don't get the meaning.
