Installation was almost a no-brainer and consisted of unarchiving the downloaded zip file into my plugins directory and activating the plugin. I then messed around with different tag cloud types for the sidebar and wound up settling on the sized cloud. The code in the sidebar looks like this:
That got the tag cloud to display in the sidebar. Rather than go with the default tag editing that comes per post when you have local and technorati tags on in the Admin Manage/Tags screen, I turned them off and added the following code to enable Ajax based tag editing to the blog entries:
And thats it. Tagging is enabled!
Just to be clear, the almost no brainer has nothing to do with the quality of the plugin, but because I was picky as to how I wanted things to work. If you want plain vanilla tagging without Ajax, the default install and adding the code to the sidebar should suffice.
