Gravatar Cache Service is a Scripts software developed by Raymond Camden. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Gravatar Cache Service:

BSEditor: The Gravatar Cache Service is an application that lets various services cache Gravatar requests. Gravatar is a web site that lets you share an icon amongst different web sites. Unfortunately, Gravatar's service is slow at times. The Gravatar Cache Service can be placed on a box and used by multiple applications to cache Gravatar icons. This can result in dramatically increased performance of applications that use the Gravatar service.
