I wanted to link my Gravatar profile picture with my account here, but it keeps telling my, that it could not find an account associated with my email address. I just double-checked, they are both the same.
According to https://en.gravatar.com/site/check/ your Gravatar is configured to be blocked on G-rated sites. I'm not sure which rating the forum requests but it's probably that, since it's the lowest.
Cool, thank you! The error message was confusing me.
