I spent the whole day trying to work out what it was that I could not remember. I'm sure that whatever it is would explain the worrying messages I got from talismancer about some dreams he's been having... but I haven't a clue.
I have a vague recollection of something happening this time last year, and the year before that. Now that I think about it... I'm sure something first happened in 2005. All I can remember from that day is Jabberwocky. There was a Jabberwock, and something... vorpal? I don't think it was a sword though.
It wasn't until a few minutes ago - midnight, to be precise - that I remembered. Ah, that explains it all.
