Today I've learned that there's a constructed language named Pandunia. I'll try to understand something better and maybe during the vacations I'll give a try and learn a little about. Now I only know the website I suppouse is the main one ( pandunia.info ) and that a esperantisto that I follow on twitter uses that too (today I have seen also that this user is also here). Is a language containing elements from almost all the languages of the world so I figurefor the major oart of humans can be easyer than esperanto or catalan or some other languages.
If you know something more about I'll ve happy to learn from you! Cheers!
