I know I can check all the threads at once by using the checkbox next to "Started by." However, I have more than 80+ pages of threads to clear, and repeating the same process is time-consuming. Is there a bot or SMF function that I'm overlooking?
How many threads are on a page for you to not just be able to hit clear all a few times (if you're clearing everything, you probably don't even need to change pages).
I don't think you've explained what you'd want a script to do better, remove everything (it's probably quite easy to make one if so)?
