What are your favourite (but little known) free Wordpress plugins?
If you have a favourite free Wordpress plugin that you think is little known, appreciated or little used, I would love to hear about it?
For example, I recently discovered SEO Rank Reporter which enables you to track your Google rankings every 3 days and view a report in an easy-to-read graph.
A fun one is 'Let it Snow' - sends snow fall across the web page.
