One my clients brought this plugin to my attention. Although running a multi-language site is a major undertaking, this plugin does a good job of simplifying the content management for a multi-language site. Some customization is required for other plugins and widgets to be integrated for full multi-language appearance, but if multi-language content is a hot item for your site, then this plugin may be worth a look.

Custom Fields in WordPress are the developer’s catch-all solution for any specific need that isn’t already covered by WordPress’s broad selection of plugins. In it’s most basic use, you can input specific content into custom fields and then present them in the post page or other places inside the loop through your theme. A good example of this is when using WordPress for a shopping cart style site. You can input all your pricing information as custom fields, making it easy for the client to input the data and giving the designer flexibility on how the information is formatted and presented. For a real estate site, the custom fields can contain a plethora of details about the property in the post. And the best part is that as these fields are in a separate location in the database that can be isolated and queried. Allowing users to request to see all single bedroom listings from the database without utilizing tags or categories.
Once when working on two separate sites that would run off two separate domains, I was looking for a clean solution to have the two sites offer the same news. I knew the solution would be in using the RSS feed of one site to post to the other. There are a few aggregation plugins out there and after experimenting with them I found FeedWordPress to be the most flexible and easiest to manage. With a multitude of options, there are a number of uses for a tool like this. The best part is that when posts are created from a feed, the plugin attributes serveral aspects of the source in custom fields with that post. This allows you to develop your theme to attribute sources and provide links to the original content.

This is a great plugin that I stumbled across looking for a solution to the free/member blog sites. Have you ever wanted to have some content be free to the public and other content that is set for members only access. But at the same time, you want to streamline the process by which users can become members of the site and access that content. WP Sentry does the trick and then some. It builds off the built in functions of WordPress to organize users and content, but tweaks it to allow a group like subscribers to see private content while hiding any sign of the private content from the public. I see this being a great tool for groups that already have membership roles, such as churches, unions, civic groups, and clubs. But I have also had requests from bloggers looking for this kind of solution to help them monetize their content.

The NAVT WordPress Navigation List Plugin has been around for a while now. It allows for full customization of all aspects of the navigation to your site. Create multiple navigation menus and simply drop them in as widgets into your theme. Although it’s a very flexible plugin, it is fully reliant on AJAX on the backend. To a lot of developers that might sound like an attractive feature, but if you ever have a JavaScript error on the back end of WordPress from any other plugin, it will keep you from updating NAVT. Other than that annoyance NAVT seems to be the leader in replacing the wp_list_pages function of WordPress.
