Where can we find forum/posts or anything to help us with these exercises?

I'm amazed there is no clue/tips or forum... Treehouse needs to fix this...

Thanks for the answer Jennifer. I was rather annoyed that when working on the exercise no link was available to find these answers. It's a bit of a hassle to go search for the right lesson each time. But thanks, this was helpful nonetheless!
