Looking at DU's stats that had a pretty active team last year from April to October, then they just vanished.
We used to have monthly posts asking folks to sign up. Somewhere I have links to our very first threads, back when we actively competed with DU and other organizations.
Or I should say that DU competed with us. FReepers started folding first and we organized as a team first, peaking at about 350 individual folders at one time, and about 1900 systems.
It was fun to see the team race up through the charts, breaking into the top 2000, then 1000 and slowly pushing our way into the top 100.
