EDIT: Yeah, it didn't work. But I think I know why! The alerts seem to disappear when you see the post you've been tagged in whether you get there through the notifications or not, so if you see it as soon as it's posted, there's no need for a notification. ...Well, that was fun.
@KatherinWinter I'm not sure that we'll be able to do anything about the post until Branch returns. I'm not sure how much longer that may be, however, as it appears that they may be recovering from a stroke as of possibly a little over ten days ago. They do appear to have posted on-site since then, but it may still be a while yet until we hear back.
