I just updated the SFN blogs to the latest version of WordPress MU (1.3.3, which corresponds to WordPress version 2.3.3) for both security reasons and the new features it brings.
Most notably, WordPress 2.3 now allows tagging — you can “tag” your posts with various labels the same way you can put it in categories. It’s up to you how you use them (or if you use them at all), but tags are a fairly big Internet fad and they’re rather handy for organization. I’m testing them out on this post.
Also, there is now a WordPress plugin installed called Spam Karma 2 that should help fend off spam on your blogs. Head over to the Plugins section of the WordPress Admin screen and enable the plugin to use it. It works out-of-the-box by capturing spam, and you can see the latest “harvest” by going to Manage->Spam Karma 2->Recent Spam Harvest.
Report any problems you have with WordPress here.
Good job!
Something you might be interested in doing is using subversion to checkout the latest version of WPMU. Upgrading then becomes fairly painless; on my own blog, I use the command
to update. Works pretty well 99% of the time and you don’t have to worry about crapping it all up.
I just have to worry about any database schema changes — if any occur, I have to run a script that updates each blog’s tables individually, which will take longer and longer every time someone creates a blog.
I’ll have to look and see how MU would handle it.
