# WordPress or WordPress MU?

 * Hi,
 * I’m currently setting up a few different sites on different domains (not subdomains)
   which use WordPress for different things (e.g. site cms, blog engine, fav gallery)
   but they need to share the same user database and cookies so that a user can 
   login at one site and be logged in at the others. Is this sort of setup more 
   easily accomplished in WordPress or WordPress MU?
 * A few possible solutions I’ve been looking at are:
    - WordPress MU and [this plugin](http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/)
      to map the different domains. (Does WordPress MU automatically share users
      between blogs?)
    - Multiple WordPress installs using the same database and different prefixes
      sharing the user database using [this method](http://opensourceexperiments.wordpress.com/2009/02/01/setting-up-a-common-userbase-across-multiple-wordpress-installations/).(
      I’m not sure how this would work with the cookies)
 * What do you think? Do you know a better method?
 * Thanks,
    Sam

 * `WordPress MU and this plugin to map the different domains. (Does WordPress MU
   automatically share users between blogs?)`
 * yes
 * When you put more than one standalone blog in the same mySQL database there is
   no connection between the blogs. They just happen to be sharing the same db. 
   Thus blog 1 is unaware of blog 2. There may be plugins that add onto that functionality.
 * I suggest you download MU and do a test install to see what you think of it. 
   make sure to follow the instructions closely. They are more involved than for
   standalone WP, especially with the domain mapping plugin.
