Real communication is essential for learning a foreign language. It helps your memory work better. On the other hand it is fun and you also learn about other people.
On this web you will find some resources to put this idea into practice: a series of essential language materials specially designed to make communication easier -grammar and pronunciation survival kits, a conversation guide organized into different topics, interactive activities...
Remember, particularly if you want to work from home, that you should NEVER give personal information such as your complete name, address, or telephone number if you are not completely sure of the identity of the person you are giving this information to.
Finally, never worry about making mistakes -they are just part of the learning process-. Simply communicate.
