what other multiblogs tool ?

WordPress :))

So where is the “Cretae New Blog” button ?

The Read Me documentation in the install archive is a good place to start. The WP documentation project is well underway, and we hope to have a lot of it in place in the near future.
You can check out the WordPress Wiki for some more information as a temporary solution until the documentation is finished.

Ok so multiblogs is possible (as everything) but it’s not a feature.
Think that it’s not the good solution if you plan to host over 100 blogs.

To clarify, WordPress does not yet support multiple blogs from a single installation. Some people fake it by using categories to simulate separate blogs (which means that you wouldn’t have categories inside any of your pseudo-blogs). But this isn’t ideal, because any user with post permissions can post to any category. The only other solution is multiple WP installs and multiple database tables (either in a different database, or in a single table, but using different prefixes in the config files).
But, true multi-blog functionality, with per-blog configuration options is a planned feature for a future release.

Thanks for clarifying that. A friend asked me about this yesterday, and that’s what I told her, but then I got worried things might have changed in 1.0.
