Just an avid reader. Mostly SF/Fantasy, some hobbies, paranormal, urban fantasy and lighter, fluffier things.
See http://www.listchallenges.com/1001-books-you-must-read-before-you-die for the list (and a possible site for echoing the no-longer-available-after-July-1-2016 Leafmarks challenges you are currently in).
I'd also suggest in addition to or instead of the listchallenges website,creating a reading list on booklikes, a listopia on goodreads, plus on any of your books sites shelves or tags for the books in the challenges you were in on Leafmarks. And sharing the links here of course.
I'm not going to make a booklikes reading list for that many books myself, but will be adding and postings ones for the Time 100, Modern Library Top 100, and my personal/friend challenges I was in over on Leafmarks. After doublechecking no one already made.
I hope booklikes will be adding more challenge and lists features (plus, of course, upgrading the discussion rooms and fixing the #*!*(#$ persistent bugs ...)
