I've proposed two new branches for merge into Postorius:
https://code.launchpad.net/%7Esumanah/postorius/bug-1157947/+merge/245979 fixes bug # 1157947 by finding all user-visible occurrences of hard-coded English strings in templates and templatizing them for translatability.
https://code.launchpad.net/%7Esumanah/postorius/metrics-template/+merge/2459... fixes bug #1409033 by correcting the messages in a template associated with three metrics.
I'd welcome any reviews. Thanks! (And I also see that Aurélien and others have a few outstanding merge proposals at https://code.launchpad.net/postorius/+activereviews , in case you want to work FIFO.)
