I just wanted to try hacking other users submission, but I couldn't open submissions.
I have locked my submissions but the submissions of other users are not shown in hyperlinks (blue underlined font) but in plain font.
When I try to double-click a score of a problem in standings page, there's no link such as 'hack it!' or sth but only the submission id.
Is it because my ratings are too low? Or lag??
If there's any full explanation about hacks, plz give me the link. Thx much
