I just joined this site today and the message says: "Our records indicate that you have never posted to our site before! Why not make your first post today by saying hello to our community in our Introductions forum." But I can't find any forum called "Introductions"! What does this mean? I can't post until I post to the forum that doesn't exist?
You can post anywhere you want, it's just to encourage you to introduce yourself. Welcome to macosx.com!
