Songsterr
This websites offers three levels of tab: beginner, intermediate and advanced. You can also search the song that you prefer to practice. I screen capture my favorite song Twilight by famous fingerstyle guitarist Kotaro Oshio as an example. You can either play the song to check your improvement or read the tab in text view. This website is helpful and powerful for fingerstyle guitar players.
GuitarNick
In this website, you can find "The goal of this new website is to provide free online guitar lessons and to help people learn how to play" here. It has four styles: Thumbpicking, Fingerstle, Flatpicking and Electric. It also has a learning section for beginners. Under the fingerstyle, it has "100 fingerstyle lessons for beginners", "20 warm up exercises", "Ghost notes lessons", "classical guitar" and etc.
I love this website because it gives you the tabs alone with online tutorials. Take Ghost Notes Lesson 6 as an example. I would strongly recommend this website.
