Pootle has an ability to check for common translation mistakes. Once you
submit a translation, it will compare its certain features with the
original string and identify potential problems. Сhecks are displayed in
the upper right corner, just above the submit button. Once there are checks
in red, you will stay on the same unit, until you have each check resolved
or muted. Note that you should only mute checks if you know what you're
doing. Muted checks will be reviewed periodically by the managers.
If you are not sure what a particular error means and how to fix it
properly, use *"Report a problem with this string"* link at the top of the
unit. The managers will try to assist you as soon as possible.
