User blog:Arrow+Pen/Quick Question...

Are we allowed to make fan continuations of fanfics? Like, on a new page? Or is that against the rules? Specifically, I am asking about: POOPIE http://battlefordreamislandfanfiction.wikia.com/wiki/Punch_Out_Of_Possibly_Insane_Entities_(POOPIE) Once In a Blue Moon BBig Brother: BFDI (Matt DB) Total Dream Island http://battlefordreamislandfanfiction.wikia.com/wiki/Total_Dream_Island

All of these, despite being of high quality, have various reasons why they will not continue:

POOPIE hasn't been edited since 2013. Matt DB disappeared a year ago. Total Dream Island's uploader said he'll move it dA.

Am I allowed to update these?

Also, I think this is my first blog post =D
