I like your plugin a lot. I am having a major problem though. I am using WPMU and I understand that it isn’t supported, but I wondering why some of your plugin works and some of it doesn’t.

I tag my posts with names of my players when they are mentioned in the post so that when you go to the player’s page it shows that player’s articles. There are only a few of the pages where this actually works here, and where they don’t work here. There are definitely tags in the posts for many of the players. I have set the threshold to .5. I’ve refreshed the related post cache.

What could the reason be?

Thanks
