View post (that green box)
View thread
I think that I figured out the green box. It seems to me that if one makes enough posts they spend plenty of $$ in subcriber fees, since it takes time to make the number of posts necessary. we get x = the # of posts needed Y= the amount of time spent to make posts & Z = the amount of money spent to reach the majic # of posts then Z= what we read when we click the green box :rolleyes:
