I had thought that after last weekend that my e-mail traffic was pretty slow due to the weather/time of year/random probability, but it turned I hadn't received any mail from the 18 Yahoo! Groups lists I belong to. Seems to be that I'm still subscribed to all of them still, but I'm going ahead and unsubbing/resubbing to all of them to get the e-mail flowing again. Haven't had a chance to research why this had happend, though; could just be one of those things.
