Was there any progress mage on this issue?
Been offline for a bit but it looks like this has been addressed. This has been fixed by @julian in commit d33d965 to nodebb-theme-persona and commit 9d202d9 to nodebb.
Hope so! Seems like there's at least one other site using this port of phpbb. Perhaps more if they cleaned out the attribution footer markup or aren't indexed by google.
I see now, I just need to add the group in. Thanks @baris!
