Hi
I made this to train RCing in F2P; in short, you have 1 account that's the "master" account that sits at the air altar and waits for trades to come in, and the "slave" accounts run back and forth between the altar and the bank and trade pure essence to the master account. You choose this when you start the script (master or slave).
It prompts you to put a username in, so it'll know to always trade the master account. I don't have it set up to trade accounts with a space in the name (it's fairly simple to do, I just never have usernames with spaces xD) so you'll have to change that yourself if you want to.
Other than that, just start with the air tiara equipped and the script'll do the rest for you.
It's a work in progress, but works fine at the moment!
