2. where does the file go
A. it goes in the very vanilla >macro folder
3. do i have to do anything else with the file .
A. yes you'll have to insert your own toons names and adjust the delays to your own situation and for how many toons you have buffing
4. anything else i need to do ..
A. yes , you will need to create a spellset for each toon preferably named the same exact thing then just insert that name of the spellset where /memspellset <nameofspellset> in the .mac file
you will have to play around with this .. but if your like me and sitting in GL and just want to hit one key and have your whole box crew throw out some MGB buffs .. :P
