Simply, it adds polling functionality to your WordPress site
This gem works out for me, as it is plain and simple and I don´t want all those fancy solutions.
Gave this one a 5 because so far in poll testing it has worked the best.
1. Shortcode easy to find.
2. Multiple voting easy to turn off
3. Poll easy to create
4. It's really free and doesn't have the hidden paid PRO version a lot of these poll plugins have.
5. If you just want to get a quick poll up, upload this plugin.
I evaluated a bunch of poll / vote plugins.
This one was the best for my purposes. Nice and simple. Doesn't try to do too much. Easy to add anywhere with a shortcode.
FYI, I downloaded the newest version from github.
