Ok, so this isn't important at all, but it's urking me enough to find out what the problem is. My countdown banners evidently expired. They were replaced with little boxes saying precisely that. So, I removed them from my signature and replaced them with fresh ones. But now these new ones do not keep track of changing time. Interesting. I created them from the same site everyone else uses (for those who still use these banners) and am completely lost. It says to use the BB code. I do everytime. And still no time updating. Anyone know why this is happening? Or not happening?

Yeah, I saw that too. It's their new trick for reducing the load on their server. The fine print on the site says:

Use these countdown sigs in forum posts, on your website or blog, anywhere you like!
All images are cached for 1 hour to avoid high server loads
Image links expire after 6 months or if there are no hits in 14 days.
