Is there a way to send suggestion or ask question other than posting in the Forum.

Check out their support page: http://teamtreehouse.com/support.

This is a snippet taken from it:

"How do I recommend new content/new suggestions? At this time you can email us at help@teamtreehouse.com with the subject line Content Suggestion. We review all emails and make note each month of what our students are wanting to see. This helps shape what we do in the near future!"

Is this what you were looking for?

I was looking for something else other than support.. It may be a good idea to and a button to send a comment to support or someone in the series you are watching. One of the series test were asking questions which were only covered briefly and I felt they should belong somewhere else. Some test questions are to brief example if you are using wampserver its it really important to ask question regarding which localhost to use with the answer being mamp or xampp and wamp being incorrect? Also had a test question where the plural answer is incorrect even though php.net show it as what it would be named. Even if you are regarding to a single item the name is still plural. I would rather post these to a private post to instructors or whoever rather than having them as public view for they are just my views which could very be wrong. Treehouse is a great way to learn for the test question do make you think and learn the subject.
