I found a bug, how do I report it?

Write to us telling us what you were doing, what you expected to happen, and what actually happened. With that, we can usually reproduce it right away. If you can, add a screenshot: it saves a lot of time.

What helps us the most

• The browser and operating system.
• The exact level or screen where it happens.
• Whether it happens always or only sometimes.
• If it happens to other people (another student, another computer).
• The email of the affected account.

We really care about these. Many improvements come from user reports, and the bugs that nobody reports are the ones that take the longest to fix. If something seemed weird to you, tell us even if you are not sure.
