redink1, there's no year after the threads with posts from January 1st. Could this be the y2k+4 bug afflicting the world that's infected our very own Dink Network? :T
Nope, its a feature (really, heh). All posts that are posted in the current year are left year-less, just to save room. It has been like this... at least since May or so, but I guess its only really noticeable about now.
