WordPress 3.0+ integrates Multi-Site feature of WordPress MU. We can easily create a lot of blogs, with only one deployment of WordPress.
WindStyle MultiSite Nav Bar can show a navigation bar on every blog of your WordPress site. All of blogs will show in this navigation bar. And you can customize site logo.
WordPress从3.0版本开始? ?并了Wordpress MU的多站点功能（MultiSite），凭借此功能，只需要部署一次Wordpress，就可以方便地创建出许多博客站点。当你在维护多个博客的时候，可能并不希望让这些博客看起来各自独立，如果你希望能通过类似导航栏的方式把多个博客连接起来，但又不想要使用臃肿的BuddyPress插件，那就尝试一下MultiSite Nav Bar吧。
MultiSite Nav Bar只需要在顶级网站中激活并? ?置，激活之后，它会在博客中添加一个导航栏，用以显示当前Wordpress站点的名称、Logo以及所有博客的链接。

This plugin adds a jQuery file that will position a fixed bar at the top of your browser screen to show announcements (controlled by a custom post type [CPT]) on each page load. Built with simple HTML and javascript.
Upon installation, you can choose the prefix for your post type. Be sure to choose wisely, because once you publish your first post this can’t be changed. If you are having problems with redirects visit your permalinks page to flush your rewrite rules by visiting your permalinks settings page (no save needed).
New: A cookie is added and deleted when you toggle the bar open and closed. Depending on the position of the bar when you leave the page is where it will be when you re-visit the site.

The Link 
Please be aware when publishing a post, as of right now, you have to fill in the content with non-html text and add a link into the link field. This link is really the permalink and is what gets counted when clicked on. It will also revert to the home page if missing, and not count against the counter. If you’re getting 404 issues when visiting the permalink page, please refer to the FAQ section.
<h3>Future Releases</h3>
