Posting with a Nickname

I figured out one way to post with a nickname. You need to create a second blogger account to do it this way. When you go to post, simply click "use another account." I had to use a second email account to do this. Then, I clicked on my original invitation from TM. It brought up the page that lets me sign in to blogger and accept the invitation. INSTEAD of signing in with your first account, click "use another account," type in your info, and then click "accept invitation."
This lets you choose a second display name for your comments.
If you set up your second email through gmail, you can choose to have all your email messages forwarded to your regular email account so that you don't have to check two accounts to get your blog messages.

(I know there is another way that a person can type a nickname, but I think that the blog might have to allow anonymous comments to do it, and you have to type your nickname every time you post).
