Display several user blog entries at once I use Blog 7.7 core module to display site updates at http://preferans.de/blog/1

However only 1 news item is always displayed at that link.

Is there maybe a way to change that amount?

I've tried looking around, including admin/content/book/settings
you can create a "view" to display a list of blogs. In Views you can specify how to layout those blogs, how many to show, in what order, etc.
NoneOne has a great screencast about learning views
