I received two emails to validate strings in the Gravatar project (https://translate.wordpress.com/languages/es/default/-all-waiting) but as I already answered (with an email too), I am not validator for that project, but only for the WordPress.com
The two emails are identical:
We’re contacting you because you are a validator on translate.wordpress.com for Spanish (Spain).
First, we wanted to say thanks: We served over 70,540,000 pages in Spanish (Spain) this week, and you helped make all those experiences better. We really appreciate your contributions (and so do WordPress.com users!).
Second, there are currently 372 translations pending from other contributors, and we’d love your help validating some of them. Could you spare some time to take a look? Validating just a few of them is still a big help.
And my response was:
I’m validator on http://translate.wordpress.com/ only for the WordPress.com project. The 372 translations pendings are for the Gravatar project. In other words, I can’t validate any of them.
However, today I received the second email.
