Thank you Moshu, that was very helpful. I think I understand it a little better now (I’m a little slow). I assumed that MU was a super powerful, industrial strength, steroid enhanced, ultra-mega, feature-wise-superset version of WP. But I take it while it does have better capabilities in terms of scalability, and is generally more “powerful” in a sense, MU is really more about serving a different type of need.
Thank you all for your help. So if I understand correctly, the standard version of WP is “multi-user” capable as well? I was under the impression for the Mu site that WP-Mu was built for handling multiple user accounts (as well as for scalability), and that the standard version was more or less for single bloggers and required multiple instances to be installed in order for it to handle multiple contributor accounts. Also, would someone be able to tell me why WP-Mu isn’t suitable for creating a multi-user newspaper-type site (or why the standard version is better) and what issues (other then scalability) is Mu designed to solve if WP-standard already handles multiple users. Thanks again.
