We have been growing at a fast pace lately, both in number of members and in number of projects. If we don't do something soon your stats pages will explode with so much information.

About the idea of splitting the new members... how about, instead of marking them in baby blue on the active stats pages, having a page of their own?
Showing for example... their points on each project, their ranking within the Team, and most importantly their ranking within themselves. And after the 7 days, they would be "promoted" to the big stats pages with all the heavy hitters and old timers.
And with a little bit of art, you could even pick 7 different shades of blue (from baby blue to dark blue) to easily see who's almost being promoted and who has just arrived.

Ok... I better stop now. I already don't wanna imagine how much work would all this be to you Ototero. :P
