First of all, figure out how to find all the users, do you want to process them all in one go or do you want to add them to a .txt file when they join/part?
Then you just wanna make a while loop to process adding points to $+(#,.,%user).
You should at least know how to add all users to a textfile, if you work that out I'll teach you how to add points to an user.
I know how to edit a user's points and all of that, I was just hoping someone was able to help make a script for what I was looking for. I'm just not sure how I would add points to everyone that is currently in the channel (at once). So like I would do "!points add current (the users currently in the channel at the time) xx (amount of points)" and that would add points to everyone that is currently in the channel and not everyone that's in the ini file. Something like that.
