I've been on here for 2 or 3 months and have made about $1.00. :D
I hope to increase this to $2.00 by 2012.
I hear some people making almost $1000 a month on here. Not sure if that's true, i hope it is.
Congrats to tritrain though - nice going.
Also I imagine high earners aren't all that willing to divulge their highest month.
