Hey, welcome, Ashlee! If you don't know what's where, just go on the home page (Here) and scroll down the list of forums. Just click the one you want to visit, and you're off! (Alternatively, go to the top of the page, and hover your mouse over the black writing that says Site Map. Then hover over the section you'd like to visit, and click on the forum you want.)
Also, be sure to check out the pinned topics. They are bold topics like rules, or how to do something.
