No, they're closed...
I kinda used to run a group under the same name, but then kind of realized I didn't like SWTOR that much, and deleted the group because I don't think it would've been right for me to run a group about something I don't even like anymore.
It's neat that someone decided to bring it back though, and I hope they will do a better job than I did.
Anyway, I think as the group owner you can set up which folders are open and how many files a person can contribute to them
I don't remember the UI and what things are called in the menus though
