Crunchyroll groups are kind of like normal user profile pages, but all the group members can post in them. It's good for groups of friends, clans, clubs, and other organizations to hang out on! There's a place to share photos, talk in forums, chat instantly, or leave comments on a wall!
Members
Members of groups can: post photos, talk in the forums, talk in the chatrooms, and post on the group wall.
Members of all groups can invite others to join the group.
Members of all groups can leave whenever they want. If a creator leaves his/her group, someone else can come and take it over.
Moderators
Moderators of all groups can change the group info and settings, approve/disapprove new members (for Closed groups), remove existing members, and add/remove other moderators
Moderators can remove or edit all group forum posts, photos, and wall entries.
The group's creator is always a moderator, the other moderators can't remove the creator.
Open Groups
Anyone can join Open groups. There is no approval process or waiting to join Open groups.
Non members of Open groups can see the group info, photos, forums, chatroom, and wall, but they can't post to any of them until they are Members.
Closed Groups
Anyone can ask to join Closed groups, but they must be approved by existing group moderators before becoming members.
Non members of Closed groups can see the group info and nothing else.
Secret Groups
No one can ask to join Secret groups, they are all invite-only.
Non members of Secret groups can't reach the group's pages at all, unless they have received an invitation (then they can see only the group info until they join).
