WordPress MU

I have installed sitewide tags plugin on my MU, which currently has several blogs, but couldn't get the compendum of the blog entries to be visible anywhere. I tried to go with a defaults first, creating a tags blog. I simply showed me its own default first entry. I then tried to point it to the main page of my site, adding a posts loop to it like so:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>

Still nothing. When I check the database I can see my wp_5, which is a global blog, but it only has default post and comment in it. I reset the privacy to make it visible - nothing.

What else I might have missed? Also, in order to start afresh, should I just drop the db tables that got created for my plugin? Or is tehre a better/cleaner way to do it?

Thanks!

It won't go back and get already published posts. It will grab new posts as they are published.

There is a one time script you can run to pick them up, but I don't have the link handy.

I realize that. I have just done a clean install of MU, created 2 sub-blogs, initialized the plugin to all defaults (using tags), andf then created several blog entries. The tags blog isn't picking them up. Anything else I might be doing wrong? It can't be because I'm working locally, right?

Are the blogs you are posting from also public?

Both are public. What's weird is that I'm checking the tags posts table and it doesn't get the new posts in it, which is what I understand it should do, so it's not just something front end tag missing.

I also though it might be because I'm not using any tags, so I created a few and added them to the posts. Nothing. This is really weird.

Can you link me to a screenshot of the spot in the Site Admin -> Options page of the sitewide tags settings area?

also, a link to your site.

I can't give you a link to the site because it's a local installation. Could this be the issue?
