So ...

We are going to use a handy plugin called WordPoints.

Here it is:

https://wordpress.org/plugins/wordpoints/

As I said, the plugin will allow you to create one or multiple types of points which you can use to reward your users when certain events occur on your website. More than that, it also includes a Ranks component, which will allow you to create ranks for your users based on how many points they have!

You can award points to users for:

• registration
• posts – you can be selective in which post types get awarded points, and award different amounts for different types
• comments – you can award points to a user when they leave a comment, and also to post authors when they receive a comment; as with posts, you can award different amounts for comments on different post types
• visiting your site – you can award points to a user when they visit your site at least once in a time period
• you can also conditionally award points based on a post’s tags, a comment’s text, a user’s role, and more!

As you can see, it's a really unique tool ...

It's a relatively small plugin (740 KB), but let's see the usual speed tests ...

Here are my results before installing the plugin ...

... and the result after installing and activating the plugin:

No more comments needed ...

Now let's see how it works ...
