I’m a tracking addict so I just had to make a profile.
I didn’t want to fill my goodreads profile with manga since I only want to track books in there, but I wanted to track my japanese readings so this is a good solution.
By the way, @Belerith, I use Grouvee for tracking videogames and I don’t know if it’s the best but if works just fine for me. You can track games played/playing/blacklog/wishlist etc. Plus set a start/end time, total playtime, rating and things like that for the games you have played.
