All of the instructions for meeting requirements and participating in a signature campaign are in the threads that the campaign manager starts. Given that you don’t even know how to access these threads is a sure sign that you shouldn’t apply to any of these campaigns, as you’ll just undoubtedly become a shitposter who will continue to flood the forums with useless posts for the sole purpose of earning money. Please reconsider joining any of the campaigns here until you could at least learn how the forum navigation is conducted.
