First off, welcome to bitcointalk! When I first joined this site, I found this link that sort of explained every rank/position. I think you'll find it an interesting read! I think Newbie accounts have access to it. Anyway, here's the link:

It's pretty informative, and helps you get an idea of how long it takes to get to different ranks so as long as you aren't spamming.

Cheers
