Since freddie has obviously abandoned this topic, I'll have to take a pitch at the dark and see if I get any answers
Okay, so I installed this hack (the updated version with the two edits in two places). Those who can't get it to show, here are two things to check:
1.) Make sure the style you want to show is user selectable. You can double-check this in the admin cp > styles > modify > properties
2.) Make sure that you "Allow Users To Change Styles" in the vbulletin options in your admin cp.
So anyway, here's the glitch I have in 2.2.8: It works for styles other than the Default. But since my default style is using the template set and replacement set of another style, it doesn't seem to show up. Only when users choose a style in the user cp do will it appear, but the style will come out blank for users who are using the default style.
This is probably along the lines of what VeloCD has
observed in his own forums.
Anyway, I dunno if it makes sense or not, but I'm gonna hold off on installing this one (maybe never) until it works
