Velocd, I do hope you check the registration date

Wouldn't it be lame if a user signed up and you prune right after that? :P
And yes, the start is hardest. if you got a board with a good crew, 10 very active members, 20 decent active members. You know it's good and will grow soon (happend to a board I was on).
After 100, 1000 is hardest, cause that's the next thing you pay attention to. After 1000, 5000 is hardest. Then 10.000, 20.000 etc. etc. etc.
