Footnotes Plugin - Looks Good, Free and Works
On my blog, I sometimes have to add in a reference source as to where I am getting my info from. I used to write the reference url, etc in the sentence and that was it.
As I was looking for a footnotes plugin someone recommended this one to me.
I was a wee bit dismayed when I read at the downloads page, it hadn't been updated for the newest version of WordPress.
Therefore I tested it on a dummy siterubix site. It was easy to use, and can be placed wherever you want to in a sentence. I think that it looks good too. It worked really well no problems.
I've now got it installed on my main site and it is working really well. Of course I performed a "just in case" backup first.
(Reminder - always back up your site before getting new plugins. Not all themes want to be friends with all plugins. Some of them get a bit cranky, and don't want to work properly afterwards.)
If you want a free footnote plugin, I recommend it. If you have a better free one, then please tell us and post a link to it.
