Hello! I have an idea. Just like replying to discussions,we should be able to reply to Photo Albums!
Example: Cyberwolf makes an Album about....ice cream. And Sadie replies to it. Cyberwolf would get a notification saying "Sadie has replied to your photo album"(just like how you get a notification saying something like "____ has like a photo album you made") (by the way Sadie comments saying "lol that's really funny") when Cyberwolf goes to see what Sadie said,it would say
"Sadie:lol that's really funny"
Just an idea! I hope you like my idea! If you don't....oh well i guess.
