We are a group of Spanish enterpreneurs creating the biggest social network for offline language learning in the world. Lingua2 is a project that started in 2008 and it has been developed since then.
If you decide to make a donation to this project, we will use the money to improve the contents of Lingua2. Do not forget to check out our apps for Android.
