Access to guidelines for ISAAC_StyleGuide_Quiz_HE denied

Hey everyone,

Trying to pass the last certification for project Paragraph Level Acceptability - English (US) - Hebrew (Israel)-en_US-he_IL

The last exam is 5 questions where you should get all questions right, but without the guidelines, it's difficult.

There are 50 attempts, tried 2 by guessing and failed.

There's a link to the guidelines, but it says after clicking on it that my access is denied.

Any idea what to do or how to contact the people in-charge? Can't find how to contact project manager and so on.

Thank you all!
