Let me clarify my previous post:
To enter to my wordpress blog, I write in front of http://
and at the end, press Enter (or Go). You will get the wordpress login page.
and here I am, inside my blog. Remember: the path for your blog may not be the same name as the title of your blog. For instance, my blog title is Linda Machado @Twitter but the url is http://www.wordpress.com/lindamachadotweets
I know nothing further how to help. It’s working for me this way.
