Yeah, perhaps I should explain about setting, it is kinda weird. It goes in conjunction with the $txt['post_topic'] setting.
It changes how the posts/topic layout is handled on the board index.

It became kinda a fad for people in their themes, so I thought why not, it'll add a new setting.

And indeed, no variable names have been changed since the last set of files I uploaded.
I assume the "Mr. X" part in ThemeStrings is supposed to be the same as the standard text strings that appear in the SMF Admin Control Center? Wouldn't it be easier to use the text strings from the available language files?
True. I would've preferred really to have used the actual strings from the other language files, but they aren't called for use on the index page, only the specific page they are on, in this case, the admin center.
