In my opinion everyone should have a Gravatar, makes your comments look so much nicer and adds a touch of humanity.
If you have a Gravatar great, if you want one follow the link, it will not take long to generate one if you have a pic handy.
Our premium member Masamir asked if there was a way to assign a Gravitar to a guest
commentator @Rich had the answer!
Would you prefer your comments page look like Picture 1 or Picture 2?
First red arrow is Pic 1, second red arrow is Pic 2
So if a visitor comes to your page and leaves a comment, @Rich has given us a way to assign them a gravatar!
The link @Rich provided can be used by simply choosing Plugin>Add New from your dashboard, then searching for WP User Avatar and installing it.
Have fun, and spice up your comments!
