I think it's just a matter of post count. The board software has the ability to assign ranks based upon the number of posts you've made.

As a side note, it looks like none of us have to worry about getting in the Beta!

Cheers fella, good work on the blog! Oh and on being promoted from Junior to full blooded Member (lol )! (how did you manage that by the way?)

I hope you make it into the Closed Beta! Good luck!
