Making each blog’s tags, site-wide (like



I’m hoping you’ll be able to tell me there’s already a plugin for this, but I’d like to join all blogs on my WPMU install in the way that have. This way, when you click on a tag on a single blog, you are taken a a list of all posts tagged with that tag on the entire install.

Thank you
