The forums are pretty user friendly. On the main forum page there is a description of what each forum is for. There are forum guidelines and your user settings right above the ad. Here's some basic info beyond that.
Click on each forum link and look at the top for the sticky posts that discuss the most common knitting problems or information for posting photos, abbreviations, etc. Lots of helpful information in those. If you still have a question feel free to ask.
To make things easier and get quicker answers when asking questions about anything include as much info as you can including the pattern name, a link if you have it, a few lines that pertain to your problem and what your question is.
You can search for answers as well if you want by using the search box right above the ad not the one at the top of the page.
Can't think of anything else at the moment...need more coffee.
