Here’s the Word Press plugins that I’m currently using:
Category Tagging 2.3. It is easy to use. The one thing that confused me was how to change the date formatting and, number of posts displayed etc. You do it by editing category-tagging.php in you plugins folder. I’m using this plugin to display related posts from the past year within the single post pages.

For example if you go to this page, at the bottom of the post you will find a set of five random links to posts from the past year in the street art category. This is because I excluded the photo category from being used for the selection, and there are only photos and streetart in the categories for this post. If I hadn’t excluded the photo category, a much less related list would display. Reload the page and different posts come up.

Akismet 2.0 is a cooperative comment spam filtering system. I’ve been using it for about five days now and it hasn’t blocked any legitimate comments and has blocked over 670 spams. You are able to check the blocked items to reassure yourself there are not any genuine comments. It is working so well that I’ve been able to turn off moderation on the comments. If it does let a questionable comment through, it most likely will be in the moderation queue and then when you mark it as spam, it informs Akismet and presumedly it will be blocked from other users.

Get Recent Comments 1.5.4 This is what I am using to display the recent comments in the sidebar to the left.

The recent posts list on the left is a widget included with the Tiga-06 Word Press theme.
