Hello I am just learning to make my own stuff with iMacros and I was wondering if someone could help me out and answer a few questions?

I just recorded a script to login to gaia and go to the item grants for Dragon & Kai, and the Hero's Eclipse, and then logout

Code:
VERSION BUILD=6311226 RECORDER=FX
TAB T=1
URL GOTO=http://www.gaiaonline.com/?logout_success=1262622636
FRAME F=0
TAG POS=1 TYPE=INPUT:TEXT FORM=ACTION:http://www.gaiaonline.com/auth/login/ ATTR=ID:username CONTENT=
SET !ENCRYPTION NO
TAG POS=1 TYPE=INPUT:PASSWORD FORM=ACTION:http://www.gaiaonline.com/auth/login/ ATTR=ID:password CONTENT=
TAG POS=1 TYPE=BUTTON ATTR=ID:signInButton
FRAME F=0
TAG POS=2 TYPE=A ATTR=TXT:Data<SP>Validation<SP>Error<SP>|<SP>Gaia<SP>Online
TAB T=2
TAG POS=4 TYPE=A ATTR=TXT:Data<SP>Validation<SP>Error<SP>|<SP>Gaia<SP>Online
TAB T=3
TAB T=3
TAB CLOSE
TAB T=2
TAB CLOSE
TAB T=1
FRAME F=0
TAG POS=1 TYPE=A ATTR=TXT:Logout
I erased the username/password - but what would I change or copy in order to do that for multiple accounts?
