Kudos!

Harrys Gravatar Cache

By default, WordPress pings gravatar for an updated image. How often do people change their image? Probably, once a month. So, one doesn't need calls to gravatar every 5 minutes. Go ahead and install this plugin. Your visitors will be happy with the speed of your site!

Thanks Harry for your time on creating and maintaining this plugin.
