I signed up for Livemocha and it seems to be very popular. They even offer a TOEFL preparation class, which will be of special interest to ESL and EAPP students. So I think that teachers should recommend this website so that students can benefit from these wonderful resources and community (and, if they have time, to review and score assignments submitted by Livemocha users).
