It still works.

This plugin hasn’t been updated in two years, and it still works. It’s pretty basic, but it’s free, you can categorize your FAQ and it’s quite easy to style. It isn’t full of shiny bells and whistles but not too many plugins are solid enough that they can go through two years of WP updates without breaking.

Five stars for not being full of over-ambitious half-done features, and for just getting the job done.
