I am amazed how we have grown. Two month ago we had 24 systems, mostly mine and my friends. Now we produce more points in a day than I produced all month.
The key to growth is indeed more systems. Some suggestions:
More FReepers!
Work computers
Family and Friends
Co-workers
Related groups (Protestwarriors, captainsquarters, etc)
For example, I'm gonna swing by my wife's 13 person office next week. With her permission, I'll install it on her 'puter. (Never install the software on a box you don't own or control, such as a library 'puter, without permission from the owner. It's a violation of the terms of service.)
