[French] I want to bring back my French

In school I learned a little French but not much. Since then I have never really used it. I can understand a bit but I can't speak (or write) it.

I would love to be able to use it at least in a limited fashion.

Do you know any good resources that might help me refresh my French?
I would be interested in both typical language learning resources and beginner-friendly content in general.

I used a book in school called Folens French Grammar that was indispensable. I think it is out of print now but it might be floating about on ebay or amazon. It was a succinct but comprehensive guide.

Thanks for your answer. I'll keep my eyes open.

I'd like to learn French by osmosis.

Bon Jour!
