Yeah, making at least $40 a month is quite a good amount, some people can't even get that working offline, and with lot's of stress, that's a good amount for one who is just starting up.Definitely, if he can combine like three forum sites he can actually make more than that amount of money every single month. if he is a newbie on the internet it is quite okay to make $40 every month because there are people that have not made their first dollar online.
