I've noticed that in my group chat, I can issue group roles to members of the group, but what do the different group roles do?

There is three different roles that a user can have in a group chat:

1) Administrator - Usually the owner/s of the group chat or someone who is completely trusted within the community.

2) Moderator - Someone who has extra permissions and you have trust in to maintain things in the administrator/s absence.

3) Standard - Everyone else who has joined the group chat.

Essentially, the settings that you have in a group chat should always be set in a way where the Administrator -> Moderator -> Standard users so then each responsibility has different powers.

You can grant a user in your group chat with a role by clicking at the top right of the group chat. You should now be presented with a list of everyone that is in the chat. If you right click on any of the contacts, you should now see "Assign Role". Click on this and now you should have the above options available to pick from for the user in question. Once ticked, you should now see that user has moved into that section which means they have now been assigned a new role.

You can alter the "Roles and Permissions" by clicking . The default options looks like this:



This is quite self explanatory in itself, but you can modify these settings depending on how you would like your room to function. (For example: You might want to give standard users the ability to "remove messages").
