Well, I am now using tags to organise my articles and posts rather than categories. If you’re reading this thinking "huh" already, then just ignore me, if not…
I am using the Ultimate Tag Warrior plugin for WordPress which seems to work a treat in adding tags to posts, when either creating or editing. It also includes a bunch of other useful tools within the admin section which keep things under control. If you’ve got WordPress and don’t have or use this plugin, then start doing so!
