My idea for a script is pretty simple yet extremely effective. Basically, I would love to see a script that makes runners deliver pure/rune essence to your main while your main idly sits next to the altar of your choice, and then you accept the trade for the essence's and proceed to rune craft by hand minus the annoying trips back and forth to the bank. I figure if all the runners are on alternate IPs and your main obviously not being botted on means your main won't get banned, and you'll also make loads of XP/GP per hour. Please let me know your thoughts and if any of you scripters would like to take on this project.
Update I do not expect this to be a local script nor should it be. If runecrafting became to easy it'd destroy the market so id suggest making a monthly fee to keep the userbase low.
