You can make a new blog, set it to aggregate all other blogs, go to backoffice and view/edit posts in Posts/Comments -> YourBlog

Or just look at summary.php ;)

Before you ask: open that file (it is in your installation's root directory) and change line 116 to show more than 3 posts per blog. Also if you want to leave a blog out of the summary you can un-comment line 104 and make sure to "continue" past the blog number you don't want in the summary. Cool eh?

This is a better solution than mine :) I always forget about that root files.

I'm probably had a really hard day... but I really don't see it...
I modify line 116 and 104 as you said. But where this list appear on backoffice?? In fact I dont see effect of the modification. Dashboard page are only for one blog, no?

Itś going to be a new page. You call it through yourblog.com/summary.php

Ah!! Thanks.
Is it possible to add RSS on that file? I suppose it's yes, but can someone could point out a doc or forum post to help to do it? I did find...
Thanks
