Welcome to Sythe. I foresee you getting 50 posts, and hanging around the Spam Forum? Making Gp is very easy. Get Rsbuddy, and do LRc rocktails, Sorc Garden, maybe Frost Dragons (they are high ban risk).
@Trackster: hopefully more than 50. And hopefully much gp to be made. I don't know if i'll be running bots anytime soon, but (@epicarrants) I have done some flipping, but made only 2.5 mil so far.
I also don't plan to become a member anytime soon. Is it worth it to keep on only flipping/merching F2P items?
