Thanks
my "Thanks" is working okay!.
Sometimes if you use the Scales Icon to approve/disprove then you are locked out of using it for that same user for a period of time ~ a week.
However "Thanks" give one reputation point and the scales can give or take away a lot more points depending upon you own green chicklet level.
It is a pretty neat system, except for the people that give tha anonymous red chcklet disapprovals.
... It encourages one to lend a HELPING HAND
