Code:
sub main
/bct MAINTOON //autogroup add ${Me.Name}
/delay 5s
/bca //autogroup load
/return
What this does:
1) From the character, execute: /bca //mac AutoGroupAddMe
2) everyone else in the bccmd channel will till the main toon to add them to the main toons AutoGroup list
3) 5s should be more than enough time for well over 100 accounts
4) everyone else will load the AutoGroup list so everyone has the same full list
