"Your school has used all its questions to the assistant for the last 24 hours. The search below still works."
Where: Help screen (/help), under the "Ask your question" field, after Ask.
Why: the school has asked the assistant the maximum number of questions over the last 24 hours: 20 questions per school, or 5 during a new school's trial period. The count is shared by everyone in the school (owner and instructors), and a question that failed counts too.
What to do: use the search on the Help screen, just below, which has no limit, or write to bonjour@martialnote.com. Each question becomes available again 24 hours after it was asked.
