How do I control who can view my blog?

By default, your blog is completely public, and can be read by anyone on the internet. However, if you want to keep it private, you can do that, too. The setting for this is on the Settings | Permissions tab.
Under the Blog Readers heading, you'll probably see "Anybody" selected as the default. When you change this to "Only readers I choose," you'll get an Add Readers button.
Click the Add Readers button and then enter the email address of a person to whom you want to grant access to your blog. To add multiple people, separate their addresses with commas.
For each address entered, the Google Account associated with that address will be given access to view your blog. If an address is not associated with an account, that person will be sent an invitation email with a link allowing them do one of three things:

• Sign in to an existing account.
• Create a new account.
• View your blog as a guest (no account required).
  

How do I move a blog between accounts?

The short answer is that you can do this by making the blog in question a team blog, with two members, then removing the original team member.
In detail, the process goes like this:

1. Sign in to Blogger with Account 1, which we'll assume is the account containing the blog.
2. Go to the Settings | Permissions tab.
   
3. Click the Add Authors button and send an invitation to the owner of Account 2, the account to which you'd like to move the blog.
   
4. Wait for the owner of Account 2 to accept the invitation. If you're sharing a computer, you'll need to sign out of Account 1 first, or each use a different browser.
5. Once Account 2 has joined the blog, Account 1 can log in again and go back to the Settings | Permissions tab.
   

How can I recover my username and password in Blogger?

If you ever forget any of your login information, just click the "forgot?" link in the upper-right corner of the Blogger home page. (Or you can go directly to the form here.)
Here you can request your password to be sent to you in email by entering your Google Account email address.
If you've forgotten your Google Account username and you've set up a Google Account for a non-Gmail address,

How does Blogger Mobile work?

You send a message - which can be a photo, some text, or both - to go@blogger.com. We take care of the rest. In other words, we auto-provision a new blog and publish the post. It's that simple.
Here's how to start a mobile blog:

1. Text REGISTER to BLOGGR to create your mobile blog. The text and/or photo in your message will be uploaded to that blog right away. We'll message you back with the address, (so you can visit your new blog on the web) and a token (so you can claim your blog and access it from your account).
2. OPTIONAL - If you feel like changing anything on your new mobile blog or if you already have a Blogger account and want the posts to go to your existing blog, you can log in to go.blogger.com and enter the token we sent to your phone. You'll then have the option to claim your new mobile blog and merge it with your existing blog. Note to users whose blog address does not contain blogspot.com: Once you make the aforementioned switch, new mobile posts will be published to your chosen blog but mobile posts published prior to the switch will not be moved over automatically.

What types of messages can I send to Blogger Mobile from my phone?
MMS, SMS, or Email - note this doesn't include email sent from a mobile device that actually passes through a webmail gateway (such as mail sent from your stanford.edu account from your phone).
