MBWorld.org Forums - new member help

As a new member, I should introduce myself. I am overwhelmed with all the buttons et all... should I push the new thread button. Should I push the subscribe button, should I push the page 1 of 205 button, should I read all 205 pages to find out how to introduce myself, do I need to use Facebook, Pinterest or the next unknown (to me) button or the plus button. I have a 1999 E320 4 Matic Station wagon and a 1974 230 and a 1976 300D. I have been working on cars my whole life. SAAB's and Volvo's most notably. Please let me thank you for you assistance in advance. Will I see this question in the new member check in forum?
