What does it mean to be active in the channel to you? And how will the bot know who is active? You need to have an idea before you make a script. Please do share your ideas and we can help you further.
For instance: "Whenever someone writes something, they get added to a list somewhere. If they leave the channel or don't write anything for 15 minutes, they get kicked off that list."
is what we want to see, so we know exactly what it is you want.
Also, there's really no need to post again after 24 hours has passed, this is a slow-moving forum, so there's no fear that your post is buried.
