I had to search for a long time myself last night to find it. See the drop-down arrow at the top next to Explore? It's part of the menu that opens when you click that arrow.
Here are the 2 specific lists. Once you've added/voted on a book in the list, you can get to them through explore>listmania>my lists (shows just the books you've voted for)>then link back to the whole list.
Flagging a post will send it to the Goodreads Customer Care team for review.
We take abuse seriously in our discussion boards.
Only flag comments that clearly need our attention.
As a general rule we do not censor any content on the site.
The only content we will consider removing is spam,
slanderous attacks on other members,
or extremely offensive content (eg. pornography, pro-Nazi, child abuse, etc).
We will not remove any content for bad language alone, or being critical
of a particular book.
I need to go add Bridge of Birds! :0)
