I just realized newer members of the UT might not understand that graphic. We started out with The Undead Thread, then the Bride of the Undead Thread (UT II), and were looking towards the Night of the Undead Thread and so on, moving every six months to a year, whenever we hit The End Of The Internet (which turns out to be posting #65534; after that it will accept no more postings).
But we started running into problems; updates on the thread were agonizingly slow. We were advised to move on every 5k - 6k postings (as the Hobbit Hole does); experience says that's about one month's postings, so we just move every month.
And because we'd quickly run out of names changing monthly, we just named it "The Spawn of the Undead Thread: The [Month] Chronicles."
And there you have the story behind the graph1c.
