ePals is a free web 2.0 resource that provides language classes the opportunity to connect with target language speakers around the globe. Communication can range from simple email messages to wiki and blog collaboration to multimedia presentations and even Skype video chat. Teachers can monitor all activity, for the sake of student security.
A potential project would be for both groups - advanced level students in the local L2 group - to read the same story or poem and then use the ePals blog tool to share opinions (targeting writing skills) and later the Skype video chat to discuss (or perhaps debate) the text (targeting oral skills).
