Before I forget to mention, are you looking for ways to practice your English (at present, most of the courses I'm talking about are in English), Spanish, or French (there will probably be other languages as more and more universities join in)?

There's this great education explosion going on in the net! It's called MOOC, short for Massive Open Online Course. It's a lot of fun if you enjoy learning. There are all sorts of university courses in a wide variety of fields, things you wanted to study but never got the chance, and it's FREE!

My favorite is https://www.coursera.org. Universities from all around the world are churning out some really interesting courses you can easily sign up for and learn to your heart's content! They already have courses programmed 'til November 2014! You can take courses in music, art, philosophy, history, economics, computers, and even statistical molecular thermodynamics. And if you don't find enough courses, you can go to https://www.edx.org and https://www.udacity.com and sign up for more!

Some courses have over 60 or 70 thousand students from around the world and you can give your perspective on things in forums and local Meetups. Your language skills don't have to be perfect. It's all for the fun of learning. So check it out!
