Hello Rodrigo,
Here's the thing, earlier we thought it was easier if you could download from
http://stackideas.com/downloads/languages . However, not many novice users really understand what the package does. Hence, we altered EasySocial so that it also includes a language section which you can use to download immediately.
In short,
EasyBlog, Komento, EasyDiscuss language files -
http://stackideas.com/downloads/languages
EasySocial - In your extension under the Languages section
In the future, we are going to move all our extensions so that it works like EasySocial and as soon as we start re-packaging our extensions to look similar, I guess you will have a lesser learning curve as well.
