Oh my God, I hadn't even thought about that. But we hardly refer to it as SLP For the love of Monsieur Saint Laurent himself, please keep YSL. I know there are some who prefer the name change but goodness me...
I like Vesna's suggestion - add SLP - Yves Saint Laurent/Saint Laurent Paris as a concession to all.
Ah, it'll be a sad day if the subforum's name changes.
If the forum is to be renamed, then "Saint Laurent" would be the most appropriate name since the House has stipulated that "Paris" is only used in the logo and not when written or spoken.
