I used to have a web site that explained this but can't find it now. Will do some checking. Basically it is what it says. You start from the desired finish and work back from there by breaking down the parts. That is it's most simplest definition.
Go to this site: http://www.pitchingcentral.com/pages/312642/index.htm. Look thru it, I think this has the info you are looking for. The free report they are talking about has some info in it. I have received that report in the past.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
