The very talented Red Head Riter posted a useful link on her blog the other day:
How To Unlike Multiple Pages On Facebook
I tried it out and it was super easy to do, so if you have ever had a "LIKE" frenzy on Facebook and want to clean up your "LIKE"d pages, give it a whirl. It is also useful just to see them all listed in an easy to read format. I don't know about you, but I often forget what I have liked and so I was able to see what was there and whether I still "LIKE" it.
Have a GREAT Day!
