Do not post answers to levels, or links to any parts of the riddle (levels, files etc.).
Do not post the full question of the level in plain text, this might help other players to skip levels. Instead, stay more general, and/or use *** to blank out contents. In most cases, the riddle creator and the players who have seen that particular level, will understand what you are talking about.
Example: If the question on level 3 was the capital of Spain, then ask for hints like this:
level 3: c****** of S****
