I just downloaded the Gravatar Field plugin. According to the documentation I dug up (see link below) when the plugin is installed it also installs a field. I didn't find the field and had to make my own. The documentation also says that if the avatar is not selected then it will show the gravatar. It could be because I had no default Gravatar field but when I made my own field I can't seem to find the settings to do this. The Avatar stays the Avatar and the Gravatar stays the Gravatar. Does anyone know the setting to do this?
Also, there doesn't appear to be an Integration Tab per the documentation. I have no idea if this is important since I don't have it and the description was short. "If you have installed CB plugin you can configure its interaction with CB Gravatar"
Lastly, I think the field is supposed to pick up the profiles e-mail and use it to get the gravatar per the documentation. Mine is not doing that. It picks up the gravatar if you put in the e-mail but won't grab it if it's not manually filled in.
