I created my first run minutes ago (it's still being moderated), and IDK if it has the timer... So how do I get it??

Download LiveSplit and watch a tutorial. Also, what made you think a timer gets downloaded automatically once you submit your run??

The rules. Like it talks about the timer.

I can't help you if you don't tell me what game you're talking about. All I can guess is that it's talking about a LiveSplit timer.
