If I'm on the forums and I see a question I'd like to help someone with these are the steps I go through.
Look at which language/course it is
Click on the house icon at the top of the page to get me to https://www.codecademy.com/learn As far as I know this is the only way I can navigate from the forums to the courses and exercises
Click on language or course exercise overview
Realize that you have no idea which exercise it is if they didn't state it in the question. A lot of users don't.
Work out how to best answer the question once you find the exercise.
Click on the Q&A Forum link within the exercise to get back to the forums. As far as I know this is the only way to get from the main codecademy site to the forums. So If i log in, I need to open up a course and exercise and click on that Q&A Forum link just to get to the forums.
Answer the question.
Is there a better way to do this?
