So, I figure we should have a thread where people can post their Esperanto-related resources to help each other learn the language. The two best that I've found are: Lernu.net - http://en.lernu.net/ Free Esperanto Course - http://pacujo.net/esperanto/course/ What have others found?
There is a Dutch esperanto group: http://www.esperanto-nederland.nl/bonvenon/index.php Maybe others can add national groups aswell, so there is an easy way to join a group and learn about the language.
A very useful greek site about esperanto,with learning resources,motives for learning,a bit of history,and many more: http://www.esperanto.gr
I'm currently using Livemocha, which is a mostly free website. A bit repetitive, but seems to be quite useful.
