Repeating a comment I left on dw_maintenance, in case this is a better place for it.

I was using Zesty White (which I believe is Core 2) and following the code change usernames were displaying fine, but the names of communities weren't displaying so instead of saying mark wrote in dw_maintenance, it just said "mark wrote under $list of tags" making it appear as if entries in communities were actually entries in personal journals, which is a bit confusing.

I have swapped to using transmogrified because I couldn't work out how to implement the change you're suggesting above - I could get to the advanced customisation area, but couldn't see any layout code that I could alter which I suspect is because Zesty White is a Core 2 style.
