For learners
Edit a review you've written
3 edits per 24 hours. The form locks once you burn the budget and unlocks automatically when the oldest edit ages out.
When the form is locked, the message tells you exactly when it unlocks — 'You can edit again in 4 h' (or 'in 23 min'). The countdown ticks every minute so you don't have to refresh.
Why the limit? Stops rapid-fire star changes from being used to retaliate against a teacher's reply.
