I receive email confirmations each time a new comment is posted, but when looking at the blog itself this morning, I realize that at least two of them aren't showing up now.
Seems that Blogger now has a spam filter for comments! Crap!
I've gone in and marked all comments "not spam", so hopefully everything's showing up now. Later today, I am going to see if I can turn off this silly-ass filter. I didn't ask for it to be activated.
I NEVER delete a comment - instead, if I disagree with one, I respond to it.
