Putting a "The End" tag at the end of the fic has been extremely helpful. I almost moved a fic, saw it didn't have a "The end" at the end, and held off on moving it. Sure enough, the author wasn't done with the thread yet. I checked a little while later, and a "The End" was there, and so I knew I could move it with no problem.
@RC--I don't need a bold name to strike fear into my enemies' hearts. I just have to give them the "Mother Has Now Raised That Eyebrow" Look (tm).
