How the community stays useful

Score earns trust. Credits are posting currency.

Neither is money. They are simple signals that reward useful contributions and give every new problem a small reason to be worth someone's time.

Score

Score is your reputation: a running record of how people respond to your work. It rises only when other people find what you shared useful.

Credits are the posting currency. One Credit lets you share one new problem; voting, comments, and solutions never cost Credits.

Sharing a new problem costs one Credit; voting, commenting, and proposing solutions are free.
When a problem you posted receives enough validations, you earn Credits back automatically.
If a moderator removes a problem, its Credit is returned to you.
