Relax! I’ll love to hear from you! For “Name” you can write “anonymous” or whatever your clever brain wants or nothing at all! (if you want to be anonymous and your email gives your name away, you might want to enter your junk email.)
I will not grab or sell your email. I only use my readers’ emails when they “subscribe” to receive myb2f blog in their own email inbox. (And I don’t sell, trade, mutilate or spindle those emails, either!) Go for it!
