seewhathappenslarry asked: I studied German for many years and even spent 6 months in Jena during 1999. Since then, however, I've not practiced as I should.
Do you know of any online groups for people like me? I want to improve my language skills but I'm not starting from scratch - I simply need a primer and practice, practice, practice.

Hallo! Why not join a German messageboard - depending on what your interests are. Practising with native speakers is always the best. As for groups, I don’t know any, sorry. german.about.com has a messageboard. But I’m not sure if that’s what you’re looking for.
