FF's the other site. I started that fic in 2003, getting up to (IIRC) 108 chapters/660 kwords, before rewriting it into 11 chapters/500k now, and it's still a WIP. And that fic is a sequel to my first fic, 40chapters/179k posted in under two months in 2003. I can't bring either of them to AFF.net because I started that first fic by basing it off another fanfic (I was impatient for an update and the original has since been abandoned about a chapter or two after I started writing). I consider myself inexperienced, though, just my nature, especially before that first fic, I thought I hated writing (buying my mother's insistence that I hated it) -- I've since realized that I hate compelled writing. Now, freeform creative writing, that I love
So yeah, dropped fics are annoying. In some cases, understandable (ie. an excellent author with severe medical issues), other times, not so much. Most are probably like me, intending to get back to my potter fic, someday, likely when I have a good looking physique, my house is truly clean, a unicorn is grazing in my front yard, and pigs have learned to fly. It's on my to-do list, really.
