is it helpful?

It is good if you have a few hours free a day, and absolutely nothing to do and you have a main job as well... But it'd be near impossible to earn a living. I reckon if you put the dedication and time towards it, and knew how to and had a blog etc. etc. you could make over $100 a week~ not bad for pocket change, but you'd have to work for it!

I do not belive it is worth while unless you have a really really big downline. It takes to long time to make the money yourself, so you have to have a dwonline to help you.
