Nah, I'll just uninstall it if it will let me, or disable it if it won't. I only get these on a couple of recipe sites, and I know where they've hidden the "close" button. It's not a big deal.
I'm wondering about the ad June is talking about, though. I've never had an ad at all on DC since AndyM (I think) turned me onto AdBlocker. Don't they have to pay DC for ads on the site?
BTW, whoever(s) set up this site did a really spectacular job. This is so easy to use. I'd list all the things I like about it, but it would take all day. Big pats on the back for everyone involved.
If you can't see the bright side of life, polish the dull side.
