Okay I have to admit it, PLN are awesome! I do not have everything completely on mine yet but this is defiantly worth using. Instead of having to go all over the world looking for stuff it is all right there on one page. Yes, I said one page! It is so easy to use and it is going to save me so much time on my homework, if I can stay off Facebook that is. I am really enjoying learning all of these new things even though it is at times frustrating. It is so worth it!
