may be i m wrong ! but as i know fiverr forum is the sub section of fiverr! i think you know that, being active in fiverr forum, its count that you r active in fiverr! so how can you say that they are different ?
i think it do ! cause whenever u will more active on fiverr and fiverr forum, they will must be notice you. and once they will rank you gig. if your gig is good enough then u might get an order !
