My posts disappeared, right after I changed my email address!This blog owner does not realise the problems caused by changing ones email address (but not the account name), without thinking.
Having changed ones email address, it's fairly easy to create a new Blogger account.
A new Blogger account lets you login to Blogger - but any blogs created under a previously created Blogger account are going to stay with the previously created Blogger account.
A new Blogger account is created - and maybe a new blog, too.
Having created a new Blogger account, the blog owner sees an empty dashboard, with the advice
You are not a member of any blogs. Create one now to start posting!and below that
Create Your Blog Now!
With no blog on the dashboard, the owner creates a new blog.
Confused, the blog owner clicks on "New Blog" - and starts creating the blog, again. Only this time, he sees
Sorry, this blog address is not available.
But, it is possible to create a new blog, with a similar name - and with no posts.
D'Ohh! OK, it won't let me have "blogger-status-for-real"! How about "blogger-status-for-reall"?
Now, the owner has a blog - with no posts.
When later he views his (new) blog, he will see an empty blog, and think that his posts have vanished. And he now has 2 blogs, owned under two different Blogger accounts.
A similar confusion is sometimes experienced with new blog owners, who are accustomed to creating a new blog, to publish each article. Only in this case, they may end up with multiple blogs, owned under the same Blogger account.
