Same permissions they used to have: Public, Members, Friends, and Private (Only Me). There is one difference though, rather than having pictures and videos in separate albums, you can now have them in the same album. Albums will also have a key like the old days.. a key you can give out so those with it can get into a private album.
Edit: Lots of work done on pictures today. Album creation/editing, image uploading, browsing albums and viewing pictures, and more.
Chat's pretty basic here. You can make your own chat commands that only you can use, but not much that everyone can use. I'm re-creating a new site (not the Owned site) the way it was in 2013 when it was super active so maybe that'll bring people back.
