I recently converted an old WordPressMU installation to the new WordPress 3.0 with multisite compatibility. WordPressMu is no longer a separate project and is continuing development as part of the main WordPress.org branch under the name ‘multi-site‘ or MS. The reasons for moving over were simple; basically it was a matter of support. Our site has become very dependant on the functionality of WordPress and our users becoming huge fans of the wealth of plugins supported. Any future improvements to WordPress could only be utilised if we moved over to WordPress 3.0 multi-site, and it inevitable to happen at some point so why not sooner rather than later.
Firstly Firebug, this plug-in enables you to pick apart websites and see how they are constructed. If you’ve created a site that isn’t quite working or aligning correctly, this tool will help you discover why. Simply install and you’ll notice a little bug in the bottom corner of your Firefox window. Click the bug to open the Firebug Console allowing you to see the HTML, CSS, Scripts, and DOM of the website. By hovering over the properties in the console, highlighted areas appear in the web browser to illustrate which part the code relates to. This is also an excellent tool if you are learning CSS and structures of complicated websites. If you see something on the web you really like but have no idea how they created it, you could to the Firebug Console to discover the properties needed to achieve the desired design/effect. Clever!
