What are infractions? Do I have some in my UserCP?
They serve as warnings. Usually you get an infraction when you step out of line.
It is kind of a way so that all the mods/admins can see you if you have been warned before, if you are posting stuff that would require a warning (if you have had an infraction before, chances are bigger that you'll get suspended
). It also serves as a warning for you to adjust your posting behaviour.
If you had one, you would know it
