Hi, and welcome to Yorkietalk! This is my favorite link,
http://www.yorkietalk.com/forums/index.php, I call it the index page, and you can find it by clicking on the words, "YorkieTalk.com Forums - Yorkshire Terrier Community". It shows all the forums, and you can find specialized information in different forums. When I got here, I would just read page after page, and learned how to do a "search" which will also be helpful. Click on someone's avatar, and that will take you to someone's profile page, where you can ask them a specific question. The how to forum is also great for learning how to navigate the forum.
