like @Dulieguy I used /mac drukamove on the chars missing the stein without using the main macro.
I followed the instructions for the char, who has to get the quest and move to the bard at abysmal.
the header of drukamove.mac I changed to:
#event A "#*#the says, 'My stinky#*#"
#event B "#*#the says, 'but she#*#"
#event C "#*#the says, 'Beer or#*#"
#event D "#*#the says, 'No matter how many#*#"
#event E "#*#the says, 'I make#*#"
#event F "#*#the says, 'reminds me#*#"
#event G "#*#the says, 'Norrath is#*#"
to get it to do, what I want.
For the first char I had an isue, because the bard at abyssmal was singning the wrong songs. I checked on zam and found out, that you can buy a couple of beer at the closeby bartender and throw the empty bottles (with right mouseclick) at him at the moment he plays his lute to get him to sing the right song.
Once he decided to sing the right song, I could with ease /taskadd all the chars missing the stein and issue /mac drunkamove to get them to abyssmal and chime in with the bard, singing the song and pick up their stein.
Nice Macro well structured and easy to understand.
5 stars for the idea and solutioin to sync the singing with the bard.
