Welcome to the home of the happily obsessed. We love having new addicts post, it makes the rest of us feel more normal.
Definitely finish the series before poking around too much. You only get one first read. Protect it. Totally worth the wait.
Make sure you check out the Newcomer's Guide. It will help you navigate the site. Meyer's Personal Correspondence is a must-read and I thought the Timeline was really interesting too.
See you around the boards!
