Comment issues

I get email notifications that I have comments and I go to Blogger to approve them and they aren't there. Not sure if people are changing their minds or that Blogger is deleting them. But if you don't see a comment you posted show up it's not that I disapproved of it, it's a glitch. I see them on my email though. So thank you to my mom & my mother in law for commenting on my last blog and sorry they aren't showing up. I will temporarily delete my monitoring until I have a reason to put it back in place (ie. an inappropriate comment from a friend or stranger).
