There is no error message, the message I got after I sign up is
"Congratulations! Your new blog, travel planet, is almost ready.
But, before you can start using your blog, you must activate it.
Check your inbox at XXX@gmail.com and click the link given. It should arrive within 30 minutes.
If you do not activate your blog within two days, you will have to sign up again.
Still waiting for your email?
If you haven't received your email yet, there are a number of things you can do:
Wait a little longer. Sometimes delivery of email can be delayed by processes outside of our control.
Check the junk email or spam folder of your email client. Sometime emails wind up there by mistake.
Have you entered your email correctly? We think it's XXX@gmail.com but if you've entered it incorrectly, you won't receive it."
