On TPF, ALL questions about authentications go in specific "Authenticate This..." threads and if they're anywhere else on the forum, they get moved (and the mods get really annoyed LOL)

So even if you put it somewhere more prominent, it would end up getting moved and buried.

I know nothing about Prada, but it seems that "Rosemary" is the designated "expert" on that brand's authenticity thread. Like here, when a mod says something is "real" most people don't weigh in any further.
