If you want to send a question, but don't want the readers to know who you are, you can post anonymously.
First, you can click on "COMMENTS" at the bottom of any post. A window will open with a space to type your comment-question. When you send it, you will have the option of using your Blogger name, which will link to your blog, a name you make up (or your non-Blogger user name), or Anonymous. If you choose Anonymous, no one will know who you are unless you decide to reveal yourself.
OR, you can send an email to email@example.com. If you want to be truly anonymous, use an address that doesn't relate to you or your name. If your email address reveals you to me, but you still want to use a pseudonym or sign "Anonymous," I will respect that choice and not reveal your identity to anyone.
However you choose to do it, keep those cards and letters and questions coming in.
