Writing correction system

Is there a screencast, help page or screenshots showing how tutors make writing correction reports? I’m curious to see the process.

Do my rankings get sent immediately to the corrector?

We don’t have a screencast to show this, but basically you highlight a section on the left, then select the mistake type, type in the corrected version and optionally add some notes.

Rankings are applied as soon as you submit them, but the correctors aren’t notified of this. This helps keep it anonymous, which typically makes people more likely to submit ratings.
