Doesn't matter, we'll still need permission from the author her-/himself.
I looked at that last line again, a little better and yes, you're right, the author is asking for someone to pick up the story. So, I have restored the link in your original post, in case there is anyone interested in picking it up. But we will still need permission from the original author for our records.
Here is a link to information how the "adoption" process works here on AFF: http://www2.adult-fanfiction.org/forum/index.php/topic/21142-how-to-use-this-forum/
There you can find the email, where we will need the permission sent from the original author.
And I would also like to remind people that AFF is not associated with FF.net in any way, shape or form.
