The offered opportunity was actually good, in fact, I got interested actually to participate in it, but when I clicked the link for Gramfree, my antivirus software was blocked it and appeared the link server is not secure, instead of continuing checking it, I stopped rather I regret in the end. I think it is not good sharing the link here in the forum that is not safe for anyone will try to attempt it especially if their pc is not protected by any of the antiviruses.
