Thread:Extension talk:MassMessage/Incompatible with existing recipient list format/reply (4)

I was a bit surprised that I had not included the category feature, so I looked and it seems like MZ [//en.wikipedia.org/w/index.php?title=User:EdwardsBot/Instructions&diff=prev&oldid=523402847 removed] it about a year ago, which is why it never got into my list of features for MassMessage.
