Niggling feeling

I had a pile of things to do that I didn't get around to doing before the holidays. I have a niggling feeling that one of those was the Oxfordshire Family History Society renewal which certainly should be due now, but I have no idea if they mentioned it in the December journal (assuming they have even sent the December journal yet), or if they sent a separate notification by mail or email, or if I imagined receiving a notification, or if I am just losing my mind! I also have a niggling feeling I had the exact same problem with the OFHS renewal last year.....

Any thoughts? I'd like to think I'm too young to be losing my mind, so I think I'll blame the heat.
