When @DannyH flowified my user talk page in the Hebrew Wikipedia, I received a rather confusing Echo email. I got in Hebrew, but it went something like: "Flow talk page manager left a message on your talk page:". There was no more text. The messages used are probably Notification-edit-talk-page-email-batch-body2 and Flow-talk-username.
This is confusing. It would be better to receive a more explicit message that would say what actually happened: "Flow talk page manager converted your user talk page to Flow", and without a dangling colon in the end.
