I started learning Japanese three years ago, but I was forced to stop after two months. Now I want to try again; what resources should I use? I still remember some basics, I'm pretty confident with kana, and know some basic kanji, but I wouldn't mind starting from scratch. Some exercises to revise the material would be nice, too.
