Gonna have to properly fill this in at some point soon.
My anime list stats and uses:
Watched: I've seen the entire series.
Watching: I am currently watching or plan on continuing within the next couple of months.
Stalled: I plan on finishing eventually - just not right now.
Dropped (With an Ep no. listed): I may return to this anime (probably not, but not at least for a few years).
Dropped (Without an Ep no. listed): (Right this is where it gets tricky) Have Dropped a prequel anime and not actually started this one. Only listed as Dropped and not Wont Watch if I have already acquired the anime in question (this'll stop me accidently downloading or purchasing an other copy in a couple of years time when I'll likely go through my Dropped Anime).
Wont Watch: Either 1: I have no interest in watching this anime at all or 2: it is unattainable / unsubbed. (I am finding (or not as the case may be) more and more anime that haven't been subbed (and that because of unpopularity probably wont be) or have been lost into obscurity) - I am listing these as Wont Watch and not Want to Watch so as not to keep searching for them again and again.
