Hi,
I think there might be a problem with the source text: when translating “Community_Engagement_Insights/MassMessages/First_message” in the fifth translation, I see the following source:

If you have already taken the survey and you wish to opt-out send an email through EmailUser feature to $email User:EGalvez (WMF)]]

I think that the last part (“$email User:EGalvez (WMF)]]”) is wrong: I should see either “$email” or “[[User:EGalvez (WMF)]]”.
