Hey, Lil' Robin,
I wanted to let you know that I had to delete your group, Percy Jackson Lovers, because of both lack of activity and members. Thanks for participating in the Kommunity, and please don't hesitate to start another group if you want to.
Also, RSS stands for "Really Simple Syndication" and wikipedia.org defines it as "A newsfeed technology that standardizes the publication of regularly updated Web works, such as blogs and news articles." Hope that helps. :)
