Make an alias, then put the code you want after the follower thing in there and it’ll do it for you… I’m surprised you did not think of this when you have mIRC connect to Twitch API with a follower notification system.
So:
on text balablabal {
alias123(stuff,stuff,stuff,…)
}
alias alias123 {
stuff code
stuff code
}
…
Etc. Fill in the blanks. Hit “F1” in the mirc client to get extra help.
It’s pretty self explanatory. You’ll figure it out.
