Welcome.

There's a lot of information to gain here, especially for a beginner. A lot of terminology and lingo to acquire. A special section at the top of the home page called the Infozone will have a lot of information for a beginner. You can also learn a lot just reading the questions and answers in the new members forum here.
Plan on coming here frequently to absorb as much info as you can without going into information overload and getting more confused. Just remember that no question is stupid if it helps YOU to understand something. Remember, there are other new vapors who can gain help just from reading your questions as they are in the same situation as you.
Once you have completed five posts and allow the forum to reset (usually within 1 hour) you will be able to ask questions and access the other parts of the forum that you can't now.
I've written several articles in my blog geared to beginners. Again, you won't be able to access it until you've completed the 5 posts. You will then be able to read these 6 articles by clicking the link below my "gun" avatar and then clicking the title of the article you wish to read.
