I have a few links I'd like to share, too! I see someone already mentioned Livemocha...I think it's a pretty good site to start with. Like people mentioned, it has it's imperfections, but they have a site for you to voice complaints on, too, if any one is interested.

LingQ. com is pretty good. They have an interesting system with lots of free podcasts. I feel rather lost sometimes because it has no grammar guides or anything...the concept is that you kind of figure stuff out for yourself as you go along.

Podcast Français Facile (Easy/Simple French Podcasts, if I'm not mistaken) is another site...the title is kind of self explanatory.

I don't think anyone has already posted those, if so, my apologies, they are here again
