As an administrator for a WordPress MU install, I’ve been getting comments about the RSS feed in WordPress not fetching the latest feeds. The RSS feed information that appears on the page ranges from a fetch that is a few hours to a day old. I’ve confirmed this is an issue with 2.9. This is an issue for blogs that need to pull alerts from an RSS feed within a timely basis, e.g. every 10 minutes.

The workaround to this is to use the KB Advanced RSS feed plugin instead of the one that’s in WordPress.

I have found a really useful plugin in Wordpress MU for making a blog private. Sometimes, committees need a way to share information away from home and they don’t want everything posted to be known by the world. Rather than using the “Password protect post” option, there is a way to only allow registered users that are members of the blog to view the post.

By default, the privacy options in Wordpress MU is limited to 1) Public, allow search engines 2) Public, don’t allow search engines.

This plugin adds functionality:
3) I would like my blog to be visible only to registered users from blog community
4) I would like my blog to be visible to registered members of this blog
5) I would like my blog to be visible only to administrators
