Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
My guess would be that it fell off something that you were carrying from your DT to either a sink, toilet, sump or other tank.
You might want to consider adding an Asterina-eating cat or dog for your CUC to extend your automated cleanup process to your floors. Either would also be useful in cleaning up any carpet-surfers that you happen to befall you.
