after 6 hours. Please help me find this widget/plugin?

I used to have a website long ago with wordpress. I remember I had a plugin which allowed me to put up a text box and user name like a widget, so any anonymous user can come to my site without registering, and blog on my front page.

Can someone direct me to a similar plugin that allows other users to do that?

Again. a plugin that allows any user to come to my site and write what they want, simply by putting in their name and text.

Again. For example: John Doe comes to my site, and he decides to blog on my front page just like everyone else. On the right side bar he sees an open text box, and user name or email requirement, and post!

Thank you in advance!
