I don't want to take a bash mate, but the one who give a vouch is a newbie, I think it will be better if you will give free signals first, for like a wekk, then maybe after that, you can charge membership fees. Just my two cents, Its not like people will give you 200$ just for trusting you seeing that you are anonymous.
Yeah I am considering making a free channel with a fraction of my calls as a trial - we shall see. All of my customers so far have been from another forum.
