Darn it, not on computer so much lol. I'll see on FAQ.
On the computer at the top of this thread, there is green horizontal bar of drop-down windows (Home, Forum, Articles, Photos, Classifieds, etc). If you click on Forum it will take you to a panel of different forums (or just hover the mouse over it and main sub-forums show as a drop-down list).
Photos can be pasted in as a link or when writing a post (Click on the Go Advanced button underneath) the post being written. Then find an editing icon (above post being written) which is a little yellow box with a mountain and sun. When I put the mouse over that, it says insert image.
Also on the top left of the website, there is a user CP button - this allows various settings, albums, etc to be edited.
