If you don't sign in to blogger and give them your email address, your comment will appear as an anonymous comment and I won't be able to email you back. I usually respond on my blog and you can check my responses then... and sometimes I'll even visit other blogs (yours) and leave a note there, too.
If you wish to email me apart from the comments section in this blog, you may do so at this email address:
(change the at to @ and the dots to .)
