<p>What's the difference between a "junior member" and a "senior member"? Is it defined by how long you've had your account, how many posts you've made, or what?</p>
<p>You're placed on a scattergraph according to your GPA and SAT Scores, and the top...I don't know, 25%? get senior privileges.</p>
<p>number of posts. i think i'm almost there.</p>
Number of posts I guess. Also has to do with how active you are.
