Protected buyer clause questions

[Gregg Fritz]

What are the rules relative to those who visited a home during the time it was for sale?  I get that those potential buyers who made offers are on the list for one year... but the people who merely saw it?

What method is your realtor supposed to deliver the list of protected buyers to you (certified mail?) and in what time frame to be able to enforce this rule if for example you re-list with another realtor and one of those families that saw the home now writes an offer?
