You don't have to sign up as a member for all blogs sites; and, for those that you do, you are usually signing up for the blog community of blog sites.
I posted the winners' list for Blogspot.com blog sites under "Winners' Lists" here in the SA forum.
Some ask you to put your email address right in your comments substituting "at" for "@" and "dot" for "." to prevent spamming! :scratch:
That is the craziest thing I've ever heard. Your email is still out their for the public to see, and I think people can figure out how to put the email back together! Uh duh!
I won't put my email in my comments. I'm already leaving them my aol address in the form, and that's all they need.
I've won many prizes from blogs; but, one time, a lady contacted me at my aol address saying that I won, but she didn't know how to contact me! :scratch:
So, I just sent her my information back.
I don't know why they want you to put your email address in your comments when you're already giving them a contact email address in the form.
Go figure!
