Simple iMacros Question...

Hello,
I've come across a script posted in the forum that I'd like to try out. I've use scripts before by downloading them and copying them into the macros folder on my computer. The script I want to use, however, was posted in the forum as text.
Example:

VERSION BUILD=7500718 RECORDER=FX
TAB T=1
SET !ERRORIGNORE YES
URL GOTO=blahblah.com
URL GOTO=Blahblahblah.com
TAG POS=1 TYPE=A ATTR=TXT:Like
TAB T=2
FRAME F=0
TAG POS=1 TYPE=BUTTON ATTR=ID:watch-like
WAIT SECONDS=2
TAB T=2
TAB T=1
TAB CLOSEALLOTHERS
WAIT SECONDS=4

How do I use this script? Do I edit an existing script and paste this in?

Yeah, Go to edit option there paste it and save it as new file.
Now, your macro script is ready

Don't mean to hijack this but can't seem to make my own thread :/.

What is iMacros really capable of. Just filling forms, clicking links etc. Or can it scrape urls / text from sites? Save all images on a page etc?

iMacros is capable of doing pretty much everything a full-featured programming language will allow you to do since in addition to their own "macro language" you can script in javascript even with the free version for Firefox. This will allow you to manipulate the DOM and ultimately do pretty much everything with a web page. You won't have "multi-threading" support with the addon version but, as a dirty hack, you can easily run multiple independent profiles (own cookies, own settings, own everything) of your browser. Plus you can take the js logic and port it basically verbatim to any real programming language (python, dot.net...) making it a great little tool to test your automation templates.

Sounds brilliant mate thanks for that.
I will look into iMacros more. Multi threading wont fuss me too much as it wont be loads i will need it for. Was just thinking of a bot like the auto queue bot something like that. Auto Follow or something, you know. But would love to get something to scrape images from google etc.
