I'm using the version 3.2.8 - Joomla 2.5.22 and my client always need facebook's conection. Almost all things work fine, but he ask about the category update. At realy, he wants display in front end the category ordering by last update done in facebook.

I looking for something like that, but I found only settings - display - general settings - date descending or ascending
Beside that, I saw there isn't the date update's option in the categories, so, there isn't the same option in general settings too

What a have to do ?

Sorry for my english. I'm Brazilian
Thank You (In portuguese: OBRIGADO)

Hi, when you import the images from Facebook, they get the new date, so they can be sorted by the date when imported but there is no function to check the date directly on facebook
