User blogs listing

Hello,

I'm working on a site that is supposed to have many users blogs and there's a section that should list every blog avaible (perhaps alphabetically sorted by username).

Drupal provides me a block with the most recent posts and also a page (/blog) that does the same block function.

I was wondering if there's any function avaible to perform this task (list every blog from each user) or will I have to do it manually (I mean create a function for that).

Thanks!
