Btw, I just realized when I checked this that there was no check at all for if nick was op to add him to the ini originally in the text event.
Replace what you have with this, and you should probably delete the ini file you have right now, considering that it has everyone who's written in the channel added to it currently.
You can simply type: /remove mods.ini
Code:
alias mod {
var %file mods.ini, %nick $iif($1 == add,$2,$1)
if ($1 == add) if (!$readini(%file,#,%nick)) writeini %file # %nick 1
else return $iif(($readini(%file,#,%nick) || (%nick isop #)),1)
}
on *:op:#: mod add $nick
on *:text:*:#: if ($nick isop #) mod add $nick
