I try and reply to everyone's comments but occasionally I get a blogger who I am unable to reply too because their blogger settings are set to no-comment reply @ whatever the email blogger is using.
So here's a tip from Allison at Stampin' When I Can
More than once, I have seen posts out there in blog-o-land about some frustration in responding to reader comments. Just in case you didn't know, if you don't set up your profile to display your e-mail address, the blogger cannot answer your question or thank you for your comments. To ensure that bloggers can communicate with you, do the following...
1. From your Blogger dashboard, click Edit Profile.
2. When the Edit User Profile page displays, ensure that the checkbox "Show my email address" is selected.
3. Under the Identity header, in the Email Address field, enter your email address.
4. Click Save Profile (all the way down at the bottom of the page).
