I just got an email from a gal saying her comment didn't show up and wondering if I'd deleted it. The only comments I've ever deleted have been obviously spam--random, nonsensical advertising. So if ever you don't find a comment you're sure you left, please leave it again!
Sometimes that word verification thing is weird (but it does block that weird spam stuff which is why I have it turned on), so follow the directions closely and check to see if your comment is published. It should publish immediately and show up when you refresh the page. If it doesn't, try again.
I love hearing from you, so keep 'em coming!
