Definetly, may want to take smaller steps, if you can for sure confirm that you able to type things in one screen and see them come up in the second screen then that part is good.

Macro wise.

There are several wikis and several people/DB-Members that macro assistance out there, basically it comes down to thinking about how you wish to setup your slaves.

There are non-focus ways, and there are focus ways, what we mean by focus, is using the /focus command to setup a main point for slaves to relate to and pull targets from, it is also the easiest way to start, imo (which doesnt account for much).

Your macros will work in conjunction with the focus command, and understand the switch/variable statements inside of the macros will help you out in the end and make it easy on your mind.

Start with basic command that has all your slaves target/focus/follow on main, then setup 1 macro either a heal or cast a dmg spell that either a) targets main/casts heal or / b) assist/focus main fast dmg spell is a great place to start.
