Hi, K_master. The Forum Rules are at the top of the page. Click there and you'll get the gist. Also click on FAQ (frequently asked questions) up there - very good info. As for the picture? You'll need an avatar which is explained in the main Welcome Center menu at the top of that page. If you're still needing answers don't hesitate to ask!
