Read this blog ! Practice your English! Come on ( venga ya)!. No deadlines (fechas tope). No exams. It's just a fun way to learn the language.
I think that is a very good way to learn English at the same time you have fun! In fact, you can meet some new people, including foreign students that I'd never speak because they don't speak Spanish and you don't know them. In the other hand, this is a good way to lose the shame to speak English, because this is one of the biggest problems for many people. You can even make friends to go out, study or spend a summer in other country!
