WordPress MU

Is there a way to have all new blogs from all users show on the front page? When I use the posts widget I only get the sites main blog showing up.

You mean all new recent *posts*.

Sure, there's a multitude of ways, in dozens of threads - there's tons of "most recent posts" plugins and widgets at http://wpmudevorg.wordpress.com, and there's also the Sitewide tags plugin where you can tell it to put all posts on the main blog.

Thanks for the response.

I have found a good plugin for putting recent posts on the frontpage, it is essentially like the built in one but with a preview.

My issue is that it is just the main sites blogs still. I am yet to find a 'Sitewide tags plugin' to put all posts on the main blog that is compatable with 2.8.2.

Most recent posts plugins for WPMU:

Sitewide tags:

you won't need both options, pick one or the other.
