How can I get all posts of one wordpress blog show up as posts in another blog ? Making the two blogs the same.
Are you wanting to copy them in real time, or just a one time job...more like moving the site? For the first, you can use the RSS feed from blog "a" to feed the stories into blog "b" .... there is a plugin for this that I think is called feedwordpress. For the second option, if you are using Wordpress 2.1+ you can go to Options / Export and export the stories and then go to blog "b" and import them. Make sure that you do proper backups and testing with these methods...they are risky. I always buy a .info domain and copy my site to it and use it for experimenting with risky maneuvers like this.
